They’re bullies and scoundrels, plain and simple. I looked at Fur Affinity, and nowhere does it say that it’s a website for people who like to rape little animals. Obviously their little pea brains can’t grasp the idea of someone being interested in animals. (Which is actually an autism thing, by the way. Many, many autistic people are
deeply moved by and fascinated with animals. I’m one of them.)
I think
@Misery is right, too, that troll moderators actually sit there looking for people they can target.
