A male friend of mine said he's going to be taking a Women's Studies class in college just to argue with women?

He will get kicked out of the class. A school really isn't a place to question and argue against a whole subject's stance. The right thing to do would be to NOT join the Women's Studies class and get involved in activism in the appropriate way - there are groups for this very thing. Disrupting a class with more than likely obnoxious and anger-laden facts will get him an F and nothing more.
