Cuz I don't really see it.

I guess you could count like the "Why do some guys not watch porn? Is it b/c their dick is small?" (posted by a guy) or the "Why are all guys pussies?" (posted by a gender troll) oh! Or the "We were at the skate park and bored so we kicked boys in the nuts lol" troll.
But, I've flagged stuff about men viciously beating and raping women, guys who were definitely serious about hating and wanting to hurt and rape women in any way, men who harassed women and girls, guys threatening to stalk girls and come to the girls houses to "teach her a lesson" and so much more.
Guy version of sexism is stupid boys trying to make fun of them and trolls. Girls have to worry about serious bodily harm, harassment, and stupid trolling on top of it. So I guess if other guys making fun of guys is misandry, there's that.1
