More women than men discuss sexism, and it is not because we find the topic more fun, entertaining, or enjoyable than men. It is because sexism gets in the way of our freedom. I blog about sexism in geek culture not because it’s my passion, but because it gets in the way of my passions.
I don't blog and care and argue about patriarchy and oppression and gender roles because I think it's fun. I do it because sexism is an obstacle in the way of a full and complete enjoyment of my life. If you had a thorn in your paw, wouldn't you bitch about it, too?
