Repeat after me:
A fandom does not define a show.  A show can be great with a shitty fandom, or shitty with a great fandom.  You can love a show and hate the fandom, and you can love a fandom but hate the show.

Like what you want to like.  If others judge you for it or say you can’t like it for whatever reason then remember that they’re not you and they don’t get a say in what you like.
