Thats why I hate greek shit. They are too concerned with saving face. Just have fun while you are in college. How could group showers and kissing be far from that. All of these things would get members disciplined.
Sororities like to maintain a chaste image, particularly for parental approval.
The sorority was almost forced to do this by the public actions of their sisters. It sucks, I'd like to change everything, but it won't change until we're a little less sexist. Even though it is a load of shit, the Chi-Omegas did not have much of a choice. I feel bad for the girls that got the boot, but shit happens. The sorority can't be put to blame.
