The way I understand it, the main thing for incels is that their celibacy is involuntary. They think they’re entitled to sex, and anyone not having sex with them is to blame for their misery. So being a rapist is precisely on brand for them, sadly.

Why is it difficult to get it? It’s inconvenient for them. Do you think people need to consult everyone else in the world and make sure that their own personal problem is the worst ever experienced by any human, before being allowed to feel uncomfortable?
