I'm sure it's not all the women there, but a handful can sure *seem* like all of them.I'd open my mouth at a time before the teacher showed up, and say some off hand comment about not being assholes and raising your hand instead of just shouting out stupid crap. And loud enough so everyone can hear. I'm sure more people would appreciate it than you think.But then again, I've been called a female dog, so this may not be the *best* way. You could just go up to the professor/teacher at the end of class and explain your frustrations and maybe she/he could say something LOUD and CLEAR right at the start, before all the yelling and shouting starts.
