good lawd, don't always be so bitter........

To address your question: Typically in movies the director will often portray a situation / group / event highlighting the stereotypes to make the film more interesting, that is to say, to gross more money for the film.

I saw the movie when it came out, I have not seen it since, but from what I remember greek life was portrayed in a way such that some aspects were overemphasized, like the stepping, while other aspects of greek life were not even mentioned, like community service.
