"Over the past decade, anti-women communities on the internet — ranging from “Men's rights movement” forums and incels to “pickup artists” — have grown exponentially. While these movements differ in small ways, what they have in common is an organized hatred of women; the animus is so pronounced that the hate-watch group Southern Poverty Law Center tracks their actions. The other dangerous idea that connects these men is their shared belief that women — good-looking women, in particular — owe them sexual attention. The incel community that Mr. Minassian paid homage to, for example, was banned from Reddit last year because, among other issues, some adherents advocated rape as a means to end their celibacy."
