That's absolutely true. Normalscum will do a lot of fucked up shit just to 'fit in'... even if barely so.
But there is something nihilistic about the blackpill. Once you realize that relationships are based solely on looks - you do start seeing humanity in a different light. Even a Chad, if somehow blackpilled, would start noticing it. Now, I'm not saying that every person would react the same. Some won't give a shit, some will obssess over it, some will just resign themselves to fate, ect. A fuckboy Chad probably doesn't give a shit that his relationship with women are 100% transactional - bitch gets a pretty Chad as a hookup/boyfriend - he gets a hole to fuck, a free ego boost, gets to feel 'like a real man', and so on.
A Chad that isn't promiscuous and wants the standard, idealized, loving monogamous relationship with a woman will be sorely disappointed, once he becomes blackpilled (assuming he ever will, kek). Personally I'd say most normiescum/beta male is in this mental mindset. They want a loving monogamous relationship. Blackpill goes directly against their needs and desires, so they reject it. Because to accept the blackpill is to accept that this idea of a 'loving monogamous relationship' is entirely fictional and impossible to achieve.
That's what lets them shit on incels without a second thought. Its unconscious. They get put off by us since we, naturally the ugly and unwelcome rejects decided to fully go against the social norm. That means we cannot exist from a normie's point of view. We are a hazard to even interact with, kek, because, god forbid, interacting with an incel could be seen as 'siding with them'... what if normie gets associated with incels? His whole 'social career' would be over in seconds, JFL.
