Personality traits are, to some extent, genetic. But because they have the choice, at any time, to improve their personality, their sexlessness is self-inflicted.
"What about disabled/neurodivergent men?" They should improve their personality. "(Most incels, btw, are center-left)" I hate the center-left...you should too, you're a dialectical materialist. I never said we should stop incels from having children, I just said we shouldn't try to help them. Literally doing nothing is equivalent to being hitler?
