Have you ever noticed that there are few tom-boys, if any, in sororities? I'm sure that there are also few, if any, lesbians. Everyone is afraid of what is different, to an extent, and sororities are no different. No girl wants to worry about whether or not her sorority sister is checking her out as they get ready for formal, or have fun in the sun on their beach day. So sororities are biased against lesbians. They have to worry about the comfort of most of their girls, so they exclude those who are different. And as much as these girls can say that they have no problem with gay people, when a lesbian checks her out, she's running for the hills.
Sororities also have a stereotypical look (which I will most likely go into more detail about on a later date) that all of their sisters apparently need to confine themselves to. Straight, silky hair, unnecessary amounts of make-up, tight, skimpy clothing. Tom-boys do not fit into this ideal sorority girl standard. And you never see a sorority girl dressed like a tom-boy. But just because of the way they dress? Yes, this is how shallow sororities can be. Rush week is almost entirely based on looks and first impressions, and I can guarantee that a tom-boy would give the wrong first impression, despite how nice and charming she may be.
How is this okay? People are so afraid of what is different that they are no longer even trying to broaden their horizons? This looks bad for American society, and it looks straight up terrible for sororities.
