Im raising a 12 year old girl and teaching a bunch of teenaged ones. I have not heard this sentiment from boys in my classroom, but I've made it very clear that I would have no tolerance for anything resembling that. The only response I can think of right now is educating the boys that it's wrong and the girls to recognize and stand together against it. Not much I can do for those outside my sphere of control, but maybe with enough solidarity against the abusive attitudes we can make a difference somewhere. Also, working to elect better people in the midterms.
