Ok I'll bite. ( even tho I raid with several ladies)
Tits lead to all kinds of drama.
Lonley guys do stupid shit when dealing with females.
The married To the tank, pocket healer shit is drama.
..... the assumption all women must be healers, and suck, leads to drama.
Young males don't cope well with women on video games.
Did I miss anything?
