In my years covering incel bullshit, I've had so many men, telling me they couldn't bear to read about them, on account of how horrifying they are. I have not had any women say this to me. This is significant.
From what I understand, it’s when an incel comes to believe that no woman will ever be with him & that part of his life is a dead end. Logically, that kind of hopelessness would feed extremism & nihilism & other nasty stuff.
