This is pretty ridiculous.
Granted, most of these alterna-genders don't exist beyond Tumblr, and I predict most people who identify with some kind of special label will grow out of it, but come on. Maybe I'm just showing my age. I didn't even hear the word "girly-girl" until I was in my mid-twenties, because almost all girls were tomboys but no one was "genderqueer". (I think class has a lot to do with this, but class is something conveniently ignored in the SJ blog world.) Note: it's okay not to identify along gendered lines too.
