A woman in the Girl Gamers LiveJournal Community states that, in her experience, non-gaming women make it difficult for her to gain acceptance as a woman who plays videogames:
But today was apparently the first time any of my co-workers heard about my hobby. You’d have thought I said, “oh, yes, I roast babies and feed them to feral cats to pass the time” for the looks I got. Honestly! There are three women there — ages 28, 28, and 55 — and not a one of them met the news with anything less than utter contempt and confusion. I truly believe that my co-workers think less of me for having a Nintendo DS in my purse — apparently the French novel, graduate degree, and work I do every day aren’t enough to mean that I’m smart or worthy of their time anymore… ’cause I like video games.
And that is the problem I have being a girl gamer. Very few men — other than a handful of cretins back when I worked at GameStop — have a problem with it. It’s the women that drive me batty.
There is some nice discussion in the comments as well.
Why can people play games like football or basketball, take that sort of stuff seriously, even play those games for a living, and not be questioned. Yet, when you say that videogaming is one of your main hobbies, it’s like, “Oh noes! You’re wasting your life!”
