wow....those "friends" of yours sound like complete arses!
Its one thing to say you don't like something but its another to say that its wrong for you to like something they don't like. Its personal tastes. You have my sympathies my friend.
As for me, I guess I'm pretty accepted for my gaming. My family don't really have any problems with it, my girlfriend is a gamer too but she's getting more into it and she even asks me to show her more titles. Hell, she's wanting to give the Zelda series a go which is awesome

Outside the family most of my friends are gamers, anyone else just ain't bothered but even if they were I've not been told otherwise
EDIT: I guess the only series I love which people are abit "wtf?" about with me is Super Robot Wars. I'm a huge mecha anime fan and not onyl do I recognise many series featured but it introduces me to more aswell. The games are all in Japanese but thanks to some translation guides it helps, plus its something to try reading once I get round to learning Japanese.
