I don't understand people's problems with Anime to be honest.
I work, have a girlfriend, go out to clubs/bars/events and lift. I watch it in my spare time just as others watch tv shows or play runescape/online games.
You shouldn't have a problem with someone's hobbies/interests just because it doesn't suit you. I could be a cunt and say something along the lines of "Nice life fgt virgin nerds, still playing Runescape even though it's a shit game". However I don't know you or your current life situation, you could be going through utter hell, and for that I don't judge a person by their outer appearance and interests.
Just remember that everyone is different. There is a person behind every computer screen. Diversity plays a huge part in today's world and you're really cutting yourself short if you aren't willing to be open and accepting.
