Why hate an entire fanbase? Even if you dislike some things that certain members of a particular fanbase say or do, those people and their actions don't represent the whole fanbase. Though disliking common stereotypes within a fanbase is understandable, but just know that not everyone in the fanbase is like that. In many cases, it's just a very vocal minority. Hating an entire fanbase is just being ignorant. You should hate or dislike the particular franchise, not its fanbase. And you definitely shouldn't hate someone for what they like. Disliking them for their actions is reasonable, but hating them for liking something that you don't is pure ignorance.
