Well it's obvious (on my campus anyway) that the people saying bad things about sororities & fraternities are the ones that aren't in them and just go by what they heard as the stereotypes. From my experience, the Greeks actually respect each other. But then again, it's anonymous. Who knows?
The stuff I read about Bama sororities I have already heard elsewhere, and I imagine that's the case for a lot of the PNM's going through recruitment at big schools. They've probably already heard rumors from friends and family. There isn't a thing that can be done, but a PNM who doesn't join a sorority just because of what she read on Juicy Campus probably already knew what she wanted going in anyway, and was therefore easily swayed.
