Woo!
Idk about that though. A good chunk of my sisters were hardline Republicans (though it obviously depends on location. I went to school in the south -- dress-and-pearl sororities, etc etc).
I'll say, with my experience with sororities in the North, at MSU, the sororities were a lot more "accepting" so were the fraternities from what I've heard, though the only one's worth joining weren't as accepting of course.
Mine was pretty warm and inviting despite being the quintessential party sorority on campus, though I was the only fully brown girl out of over a hundred.
Okay maybe those two thoughts are a bit contradictory....
