I'm a straight, cis, thin, able-bodied, white grrrl. I learned one day that someone can't just call themselves an ally, even if they support people who experience other oppressions. It needs to be a constant process of learning and fighting against other people with privilege. So I'm here to do that learning, through lots and lots of reading.
Oh, and also, while you should never expect people to educate you about their oppression, I personally am totally willing to educate dudes about sexism. I will answer every question asked of me, unless I one day get too many questions to do so.
