Well, just jumping in here, I can't speak on alot of stuff being said here...however, I will speak on the original point.
My chapter at my school (lets just say that we're in the very deep south), we are the first IFC chapter in our school's history to admit a "minority student" into our ranks (black, but, that doesn't matter) and will hopefully be adding several more this coming year (because they're a bunch of good guys)... maybe it's just because we've re-colonized here and we find it so much easier to go against the grain....
That being said, I have a good friend from back home who is closeted gay and I would very much like for him to pledge here. All my brothers who have met him love the guy, even after they found out that he was gay (because he wanted to say that up front, no secrets). ...then again, maybe they all love the guy because he could probably beat every other fraternities intramural teams by himself.
