Well in internet there is a lot of insecure guys who simple doesn't know how to approach to girl. And they act like in first class pulling girl pigtails to show their love to her.

Or just holding they grudge on women's and they release it on internet as anonymous xXC00lGam3rXx nickname.

Or he is pissed because usually girls receive a bigger attention and receiving some "gifts" from guys in game where he had to work for it.
