AHHH!!!
Don't even THINK about taking that stuff serious. The whole size two/blond/etc.etc.etc. garbage is not accurate. Think about the whole population on a campus. If you put the whole Greek system in a single file line, you would see a fairly accuate random sample of that campus. Of course, this differs from campus to campus, but for the most part, you will see a variety of "types" within a given group. You will also see guys and gals that don't fit any mold at all.
If being size two was a requirement, quota would have to be about 1. Total would be 3. Real women become sorority women.
