If you’re like me, you cringe when you hear the word “incel” and never use it without scare quotes. Of course, there have always been people who are involuntarily celibate, but when they band together as a named subculture, something’s seriously amiss. I’m pretty sure I’d see it that way even if there weren’t four recent cases of men venting their sexual frustration by slaughtering people—one having done so explicitly as an “incel.”
