A surprisingly high amount. Given by how every single post where the dude makes a risky joke is filled to the brim with "bro you're so dumb, you ruined your chance to get laid", this place is very clearly filled with a lot of young men.
Sexually frustrated young men also happen to be extremely primed for indoctrination by incel/red pill talking points. I should know, about ten years ago I fell into that trap myself. When you're lonely, angry, depressed, young and naive, it's very easy to be like a moth to a flame when someone comes along and confidently claims they've found the solution to women and dating.
Basically, this sub is rife with people who are just a few wrong clicks away from getting red pilled.
