I can't help but think that a lot of resentment from guys who aren't getting laid comes from society's notion that if you can't or don't get sex, it means you're a lesser human being and that makes it okay for others to hurt you. In that position, I could easily see a man resenting women as the gatekeepers of his full humanity, and that by not having sex with him, they're depriving him of it. It's very similar to some angry thoughts I had when I was younger, and in a worse timeline it's entirely possible I could've fully plunged into that same cesspit.
That isn't to justify any of the awful shit that incels say and do, of course - many reactionaries lay blame in the wrong place for very real problems they face - but I feel there has to be a connection there.

agree, I only say "incel" to mean specifically the assholes who post on incel forums and who hate women. but to some people it simply means "virgin" and to others it means "misogynist". the term is so over-saturated in culture now that it's hard to have an honest conversation about it
