I think it stems from an idea that since the incels are so deprived they would accept anyone so they think women should/would too. In reality maybe women are getting attention way more often, but it’s from gross (not just physical, but sex pest and whatever) people you’d never want to be with so staying single is preferable.

They would see this as being “too picky” and they could be with someone if they really wanted to, completely dismissing the reality that no one in their right mind should settle with some schmuck like me lol
