I feel like we should stop calling feminists 'feminists' and just start calling people who aren't feminist 'sexist' - and then everyone else is just a human. You are either a normal person or a sexist.
And it happens at my school too. I guy was in a shirt that referenced sex and my shorts were only two inches above the dress code and my teacher pulled me up I front of the class and slut shamed me. Christy was the teacher)
