"Diane shot holes in both feet with that part about the unfairness of girls denied makeup and miniskirts in school. I am not carrying any signs in any marches for the right to amplify sexual allure in classrooms."

Haha, yep, I think she was just casting about for any example of women's oppression she could find. I'm sure, in another context, she'd have been talking about how wrong it is that young girls are sexualised. Agreed on school uniforms. There are lots of benefits to them. For example, poorer kids don't have to try to keep up with fashion at school which reduces the chances of bullying.
