I sometimes get the whole "You don't need any more games" stuff from my folks When I started dating my girlfriend, the folks said "oh, now you won't have time or money to waste on games". When I started looking into my house deal, one of the things that came up was how I wouldn't be able to afford a ton of games. So, I don't think they're really supportive of the hobby, other than being the ones that started me on it in the first place.
At one point, I didn't mention any of my hobbies to a lot of people because I thought that it would make people think I was strange. But the older I get, the more I don't care what people think. It used to be, if someone asked me what my hobbies were, I'd just mention artwork stuff and bass guitar. But now if someone asks, I say what I do, and not worry about it. If they are into gaming, I'll even mention VGCollect to people and rattle off some stats off the top of my head about it. If not, I'll make conversation about other things and let the gaming stuff slide.
And gaming did seem to turn off a lot of chicks when I was growing up / dating. Hell, when I first met my girlfriend, I didn't mention anything about gaming, mmo addiction, Magic cards, mini painting or anything "hyper nerdy". I was even super unsure about bringing her over to my place, just for the fact that I have it all out on display (You've all seen my living room, it's overwhelming to some people). But she actually thinks a lot of it it pretty cool, even though she's not a gamer at all. I've had her encourage me to pick up things I was looking at and cheers when I add something new to the Castlevania shrine. So, I guess I got lucky.
I still don't lead with "I'm a gamer, deal with it". But I'm with Kimimi and say don't let people dictate what you are into and if they don't like you for who you are, they aren't worth it. Of course I'm not going to let anyone tell me I can't play games.
