I don't know any women's studies majors, but we have a similar issue at my school. The people who are in CCM, the music & dance college at the university of Cincinnati, get the same prejudice about being in a GLO. I'm not a CCM-er, but the ladies at my chapter who are get the "
you're in a

sorority" comment a lot. They reply "Yes I am." & go on with their life. If people in your major are so independant minded then they shouldn't mind you blazing a trail for other women in the program. Do your own thing & don't worry about it.
Best of luck
