Well, I never thought you hated her, but at the same time, friends have to set limits. I understand your lack of a desire for a fandom!war, though.
If she's the kind of person that's always judging everyone, though... is she a good friend, then? I used to have a really close friend that really just kind of... looked down her nose... at anyone that disagreed with her theories or tastes. We're still friends, but we're not so close anymore.
I don't know if your friend is like that at all, though, so!
