I believe that work of fiction is fiction and it should be trated as such. So who cares if there is rape, pedephilia, zoophilia, tentacles, cuckolding and other things? I's just a fiction, get over it. All in all I prefer to let them have this stuff in game jerking off to this rather than having them go out and trying it in real life.
Also if it isn't evident from this statement, I don't support censorship of fiction of any kind.
Soo... in other words you want to control people's minds? You do realize that it isn't people's choice to what they are attracted, right? Controlling people's minds and forcing them to think the way you see fit would be more disguting to me than them having their fantasies.
