Op, if you never talk about it, you will never find a person who likes it as well.

Here's a suggestion- find a key ring, button, etc of your favorite anime. Something small that you can wear around without raised eyebrows. You will be surprised how many people will say they like it (depending on the places you go, of course)! And if a person starts making snarky comments, you could say it is a gift from someone and you thought it was cute, and can back up quickly.

In many cities anime has become kinda-sorta mainstream. I can't remember the last time someone looked down on me for liking it!
