Every time you feel put down, demeaned, hit on, or harassed because of your girlness, you have the option to internalize the message that you don’t matter or to say out loud that you’re not going to take it and give the shame back to the offenders. We’ve got to get one another talking about the things that bother us and the ideas we have to change them. Tired of the catcalls when you walk past a construction site? Organize a group of girls and women to show up with signs that let whistlers know where they can put their sexist behaviors. Feel like a certain teacher favors boys and belittles your classroom contributions? Enlist some girls to stage a walkout with you. Every time you stand up for yourself and other girls, the ability that others have to disparage us gets even smaller.
