If every incel somehow got a girlfriend, the net violence in the world would only go up. Because guys who think like this are violent to their girlfriends. It's not their singleness that's dangerous; it's the way they think about women.
So, Incel stands for "Involuntary celibate, and is a group of misogynistic assholes who blame everyone else and women in particular for their inability to get laid? So what's the term for good-natured, lonely guys who realise we are just geeky shut-in losers and own it? Lol.
