It's mostly a cope. I grew up treated like scum, yet I can open up and be a very normal person you'd never think purely socially. IOW, you think it's some "deep-seated" damage but the truth is it's only merely human instincts and nature at work AKA no reason to be extroverted and outwardly open when your looks have set you in to the firm place of low-value nothingness from your own life experience bare bones.
Not being "NT" is just a way to gaslight -- to pick you apart and find alternative excuses usually to mock you for. You know, why is Mr. Loser 36 and stupid and lonely and smelly and etc.? Oh yeah, it's his social skills! Forget why he hates society -- just blame him for not subjecting himself to it despite any valid reasoning behind his choice, conscious or not, to isolate and/or never manage to fit in!
I had so many things made fun of when I was a kid, only until I got older and looked a bit more masc. which is when people, especially guys, stopped fucking with me. But NT is laughable as some think it's the difference between a slaying Chad and a basement-bound truecel when that's almost never the case. Sure, with looks you benefit from at least half-decent social ability, but the best social ability never replaces LOOKS.
Even socially anxious Chads or guys with good looks I've seen almost always will end up having sex/options at least even if they never go through with them. On the other hand, plenty of guys here, including me, can emulate the normie NPC script to a T but still not get the high quality experience of it. I know I could jester more and get some social improvements maybe, but I'm not subjecting myself to 5th wheel life treatment.
I mean, sure, you can probably clown your way somehow to being the punching bag jester of the group, but you'll never fake genuine respect from others. I do not talk to people much usually, but I have no fear of talking to someone, anyone, if I know they want to talk to me and treat me right. AKA most people actually have at least acceptable social ability -- it's more the CONFINES or CIRCUMSTANCES in which you can actually show it/shine. Since us incels are known for being treated like second-class citizens we are tainted with well-reasoned but obviously detrimental negativity in how something will work out for us -- but this is a good thing because it's RATIONAL and HUMAN to LEARN and ADAPT/etc.
