Something I've always wondered is what kind of women were in the lives of incel men when they were young. Did they have a bad relationship with their mother? Did they lack sisters or other female family members? Or is their family situation irrelevant? Maybe some particular situation in their early years caused them to develop a complex around women?
I was borderline incel. Viewed positive female peers (family, etc.) as completely different from "tainted whores" or whatever.
Bad experiences, chronic isolation are what make an incel. Lonely men without supportive friend groups who turn to the Internet for their social needs. Rejection and dismissal from real world people, acceptance and empathy from the hive mind.
Loneliness does a lot more damage than a shitty upbringing.
