That's weird. I've played Xbox since I was 15 and move guys are excited a girl is playing with them. I've never once been put down for being a girl gamer, mostly embraced.
I guess it depends what games you play.
But, I do get embraced for being a female player as well, and also get creepy messages which I don't like.
And because I have Japanese in my name and my bio because well, I am Japanese I get a lot of racist comments too.
Usually when people are out of line and send me rude messages I just send them a ";D" in response because I don't care about random people over the internets trash talk.
Or, I'll go off in a long Japanese tangent before leaving their game lobbies. Haha
