Conversation of ur fandoms to ppl?

I just joined so like hII!!

 bUT I wanted to ask if anyone else has had to not speech on their fav fandom bc ppl hate it THAT much yknow? I know the moment i mention Homestuck or Junjou Romantica its usually over on making a new friend online,,. :p oR like when you bring them up how do you introduce them as to see if that person is gonna be mean, (i swear it gets so hard sometimes)
