Asking here because it's ridiculously hard to get help in the UK.
I've had this strange numbness in my hands for the last 2 years, which seems to be brought on by cold weather, and overuse of my hands specifically or gripping for a long period of time like on a steering wheel. It also seems to stem from my back because I feel a craving of sorts to crack my back whenever it comes on, and I suspect it's a trapped nerve or something like that. But I do also have a history of amphetamine abuse (1 year clean now) and alcohol abuse (several years clean), along with many genetic disorders like asthma/hayfever, a schizophrenic parent (I have no symptoms as far as I can tell), and heart disease (I do experience heart palpitations quite regularly and considered it "normal" for a long time) killing literally every single male in my family before they hit 65.

So at this point I just want to know why it's happening, and don't care if it's treatable or not. My initial suspicion is a trapped nerve, then possibly a heart issue, and finally psychological issues.

It feels like I've lost complete control of my hands sometimes, even though I can still move them, they just feel dead. I just fear that one day I might actually be paralyzed or something.

It is literally impossible for normies/glowies to understand or research 4chan in any meaningful way, the best they've ever managed is literally just slide threads which are almost immediately btfo.

What are the political implications of 4chan anons managing to subvert all attempts to investigate us, and why is /pol/ so powerful?

I know you're being contrarian, but you're actually right and don't even know how.

If you imagine the distribution of political ideologies it may look something like pic related.
Republicans in red will fall somewhere on the line, where a left leaning republican will be in the middle and an "alt right" will be far out on the right edge. This forms a bell graph represented in red.. Ditto this for the dems represented by a blue bell graph. MOST people whether dem or republican will fall somewhere in the middle. There is much common ground and much both sides share in common. This is important because this is how both sides work together, cooperate, and form compromise when disagreements arise. The ones on the edge share nothing in common with the others on the other edge. For these people where there is no commonalities or common ground, compromise and "working together" becomes impossible. There is a concerted and coordinated effort to drive a wedge in American politics so there is less and less middle ground. This is an attack on America. It is a "long game" strategy from nations that hate Democracy and American in general, and wish to see it in a state where it's literally impossible for anyone to work with anyone else. This gap has grown in recent years, not because people have inherently changed, but because their elected leaders have changed and are leading them in this direction.

So what do "alt right" and far left wing have in common? Those are the "extremists" who are not capable of working, as as they're not capable of compromising, may be forced to settle disputes with violence and force. Extremists can easily become terrorists.

we found out about trannies

Summary: any species-bridging mutation is necessarily going to be evolutionarily disadvantageous and this can be deduced simply from the definition of species. Hence it is impossible (or at least extremely unlikely) for one species to evolve into another.

Argument:
The evolutionary narrative implies as a matter of logical necessity that an individual from one species at one time gave birth to an individual from another species. Incrementalism doesn’t save you here, for we can simply perform a thought-exercise to show that what I am saying must be the case: take any individual from species B and ask “who was its mother?” over and over again. If species B evolved from species A, we will eventually get to a female from species A giving birth to an individual from species B. We can designate this individual “B1” because he’s the first individual from species B. Now, the definition of a species is the ability of its members to produce fertile offspring. If B1’s mother was from species A, and B1 is the first instance of species B, then it logically follows that B1 WILL HAVE NOBODY TO REPRODUCE WITH. Since species B cannot produce fertile offspring with species A (as per the definition of species), nobody in B1’s community is going to be a suitable mate. Unless, by some magical circumstance, someone else from species A, in the same area as B1, also has offspring with the exact same mutation and gives birth to B2, and then B1 and B2 get together and reproduce; unless that improbable circumstance occurs, species B is bound to die out immediately. This argument is one of the strongest proofs against evolutionary theory, and I’ve never even heard anybody else use it.

>Her ancestor from 600k years ago could breed with her. Then go to 1.2 million and so on and so forth. You probably can't breed with a human from 1.2 million years ago
>probably can't
Ring species concepts are nonsense and on top of that you're adding in speculation. Provide evidence of this. Saying "probably can't" is not evidence.
>Species only exist within one specific timeframe
You forgot to add "probably"
>The transition from one species to another is a gradual slow process with no direct cut-off.
You are arbitrarily deciding the time frame. Above you chose time frames of 300k years, 600k, then 1200k etc. That is clearly a multiple of 300k years. Why? Let's make it 100 years. Nothing changes in your argument and viola we now have "transitions" from one "species" to another "species" rapidly. Since interbreeding doesn't matter you are left with nothing except your arbitrary time frames to demarcate species.
Going slightly beyond the scope, punctuated equilibrium is also a theory that directly contradicts your arguments here. If species in the cambrian explosion paradoxically went from sponges to complex eyes in 20 million years then it's certainly no jump in logic to think reproductive isolation can happen in just a few thousand years and after that have long long periods of interbreeding.

I'm not wasting time, the genus Canis and its species is well established. A 4chan retard without sources cant change the phylogenetic tree to his own convenience.

Genus Larus gulls are the "type specimen" but data was a bit ass to get conclusive, Caribbean Euphoriba are the proper proof case. Seems to be more common in plants, for some reason.

The way it works is basically that the differences slowly result in garbage minutia conflicts which slowly reduce interfertility, until eventually it's genuinely non-viable. We're pretty sure that the first generation of Sapiens/Neanderthalus humans were incredibly fucked on a fundamental level.

You don't have to bloviate with all that you can just say "I'm not allowed to think for myself and must consult my masters and only repeat their dogma"

And they should be considered mixed breeds. It's very simple.

>Caribbean Euphoriba are the proper proof case
?? Of what? A"Ring species" is allegedly a connected SERIES of, possibly dozens, of species. It makes no sense to point at just one species. Do you not know what a ring species is? It honestly should be called a "ring genus" but it's hogwash anyway so who cares. Garbage pseudoscience tends to get basic things wrong, like a valid name of itself. It's not at the species level nor is it a ring, it's diagrammatically shown as a horseshoe ROFL.
>Seems to be more common in plants, for some reason
Sure it is.

>The way it works is basically that the differences slowly result in garbage minutia conflicts which slowly reduce interfertility, until eventually it's genuinely non-viable.
ROFL I know the conjecture behind it. You don't have to repeat wiki you probably read for the first time just now.
>We're pretty sure that the first generation of Sapiens/Neanderthalus humans were incredibly fucked on a fundamental level
>pretty sure
There it is again ladies and gentlemen. Conjecture presented as evidence.
You missed the point of the post anyway. I wasn't asking for evidence showing a ring species series exists.. I was asking for evidence of the alleged fertility issues that was obviously made up to fit his argument.

Why does the 'qualia' argument even exist? Language hasn't evolved enough to describe conscious 'feeling' states in detail. At most, 'qualia' is just an abstract noun. It means nothing by itself and it's commonly misused to describe other traits of perception, such as color or perception of pain, etc.

Every societal, or social, or embodied event can be described deterministically. Pink noise selected out of phase space transitions, according to chaos theory allows for a compatibilist theory of free will. ERP (Event related potentials) can be measured using semantic primes. We can objectively measure the emotional content of a word, gesture, or the neural correlates evoked. Gestalt theory and cognitive heuristic biases determine how we memorize new material.

For the rubber hand illusion, bottom-up perception overrides top-down consciousness, therefore body ownership can be transferred. Botvinick and Cohen regard 'proprioceptive drift' as evidence in favor of a connectionist model of trimodal processing with all three sensory inputs. (vision, proprioception and touch)

So again, why does this 'qualia' argument exist? And why do people believe consciousness can't be described in materialistic terms? Is this just a misuse of language?

You're fundamentally wrong.
The only we know for certain to exist are qualia. We are aware of or experience sensory data.
Then we invoke the Principle of Sufficient Reason, and use abductive reasoning to select the most suitable theory to describe their cause.

But determining their physical cause has left us no closer to understanding the details of their identity.
What are qualia exactly?

I have my own theories on the topic, but it involves a philosophy of Idealism. (Everything is idea or thought, in the mind of a God).

The "axis of evil" is a name given to the apparent correlation between the plane of the Solar System and aspects of the cosmic microwave background (CMB). The anomaly appears to give the plane of the Solar System and hence the location of Earth a greater significance than might be expected by chance – a result which has been claimed to be evidence of a departure from the Copernican principle as assumed in the concordance model.
