PMSL. No. I've never in all my life met anybody who could be called an incel who remotely approached the left side of the political spectrum.
I've met a handful of ableist or racist assholes who would be otherwise left-wing, but generally I find incels and RWers tend to share the same "I'm all right Jack f*** everybody else, if they can't take my hateful jokes they have no sense of humour" kind of crap.
LWers don't blame society instead of themselves for crap. That's a heavily RW attitude, actually, which is why they assume LWers do it the same way. In actual fact, most LWers will point out society's flaws, but they usually admit that they're not blameless either, and say that the problems are something everybody should be concerned with. So they blame society as well as themselves, nine times out of ten. The "me first everyone else last" types don't like that. Not one bit.
(edited to fix tags.)
Right wingers tends to look at practical solutions to fix problems. Left wingers look at victims and make themself into one, so it must be the systems fault.
Nah its totally left wing. I am not convinced at all that its anything other than that at heart
