Just yesterday, my teenage daughter (not trying to say anything about your maturity level here) said to me that she didn't like it when I talked about anime because she thought the word was embarrassing. She really likes anime, but she is embarrassed about it because even though she knows anime is fairly mainstream now, she likes more obscure stuff.

I told her that apart from it being a perfectly acceptable word to describe the art form both in and outside Japan, if you spend time worrying about what people think of your interests, you're wasting time you could spend on those interests- and actually stopping yourself from doing it. And then while you're doing it, you're wasting time feeling bad for enjoying yourself when you could just be enjoying yourself.

On top of that, if a friend is going to judge you for your interests, maybe they're not really a friend. And everyone else? Fuck them. They have to share the Earth with you regardless and if they don't like it, that's their problem.
