I think the internet can act like an insulating force and for certain people a viscous feedback loop. Like it’s far more easy for certain types of personalities to call themselves “incel” and whine about it on the internet than get out of their bubble and talk to people. The insularly force is clearly amplifying other communities so this is probably “just another” instantiation of the same effect.

Edit-I don’t know the best way to exit this problem. But I’d probably start with telling the disparate groups that their positions are not so abnormal and maybe they would be happier focusing on other things-like hobbies that require time offline. Have your “incel” days and have days you force yourself to do something, anything else than think that.
