"Rape is horrible! Men are rapists! Therefor men are horrible!"

GS is a show about a male exclusive race that is born evil and inclined to rape, and how horrible they are… and how good it feels to cleanse the earth of them

"I HATE IT!"

Keep in mind most of the offended party are twitter users who only watch basic anime, not the other stuff.
So when GS appeared, and just showed rape and violence, people immediately decided it was shit just for free replies.
