Coming from a perspective a BGLO: On a predominately majority university, I agree with Heidi Ho, if it wasn't for greeklife I'd really feel alienated out there.
But the fact that I attended an undergraduate Historically Black College/University (HBCU), some may say it segregated the non-greeks vs. greeks. That was what Spike Lee's old movie "School Daze" was about.
But, most of these schools are so ingrained into greek life with so many folks being in a BGLO--meaning, professors and students AND the fact that we have such an active alumni participation in the greek experience--at least IMO, the anti-greek sentiment was quelled or even silenced. Basically, we greeks would say to an GDI's (God damn individuals) that their anti-greek hatred is only because they really wanted to join an organization, but they were denied...
To give you the greek and HBCU flavor, during Black college football classics, such as the Bayou Classic in New Orleans, it would be sacrelige (sp.) to NOT have a "step show"!!!! And the HomeComing Queen had better be in somebody's sorority... And it wouldn't be summer if the "philly Greekfest" didn't happen...
I don't know how these things came about.
Your paper is gonna be rather interesting.
