Hating something because of it's fandom or the hype

I can't fucking stand people who hate works because it's gotten "too popular" or the "fandom is too cringe". I don't mind when people hate shit just because they don't like it, but when people start hating stuff cause it's "overhyped" or they don't like the fandom it's just so fucking stupid. It's so elitist. Can't you enjoy something or hate something using your own fucking opinion without being persuaded by a community? Terrible people in a fandom exist for literally every piece of media and literature just because you don't see it doesn't mean they don't exist.
