Rant time!

Okay so in creative writing class, my teacher assigned us to create power points about real world issues. One of my friends did hers on rape. My teacher interrupted the girl and then said "I feel sorry for boys because it's hard to listen to no when you girls dress like that! You're bringing it upon yourselves". Another girl told a story on how a girl got drunk and was raped by her boyfriend and his friends. My teacher said "well none of that would have happened if she never got drunk."  She was being really rude and saying that boys can't take no for an answer if we dress a certain way. Do you think I'm being too sensitive or is it acceptable for me to be mad?
