I live in rather small town and am pretty confident that most people think that games are simply a waste of time and childish. To some extent, this might be true but at the same time they should be in no position to judge me if they watch shows like Keeping up with Kardashians, have purchased Big Brother 24/7-service or any other similar stuff. These seem to be more justifiable, because of marketing towards younger audience to create new "cool" and "in" things. I don't judge those people initially, but I can point out double standards.
On the other hand, I wouldn't go and make a date profile and highlight the fact "I am a gamer". If the possible match does ask what hobbies I have, I might mention that I play videogames sometimes. If it is a turn off for her, it is actually my victory, since I don't want a partner with narrow mind. Gaming does seem to have certain social stigma, but you don't have to play only by yourself and you might find new friends, even if they do live further away. It should NOT be any less acceptable than simply going to bar, grab few drinks and talk random stuff, then find one-night stand, go back to home or whatever. People like different things, but not everyone can accept that. I can exercise while gaming or watching anime and it has improved myself so it certainly isn't a completely waste of time to me. Someone doesn't like that? The door is over there.
Humanity isn't evolved enough to get rid of negatively judging attitude or the need of acting like superior person. People are still ignorant. Gaming world is vast enough to ignore racists, misogynists and sexists, but of course people notice them because they are louder.
