Of course you can. My wife is a much better raider than me, and our guild is at least 33% women.
But when drama gets started, in this guild, or any of the past 5 I've been in, guess who it was by or over? I'm not saying it's a blanket. I'm saying it's how it is in my personal experience. You also don't have to be a fat white nerdy basement dweller to be a guy. And people with tits can apparently stereotype with the best of them.
