Going to a party or bar in the college atmosphere, brings with it a pressure of sex and alcohol, which the two do not combine for the good of humanity. The alcohol only stimulates a persons mind to due acts that not normally would be attempted. Acts such as sexual intercourse and sodomy as such. If this is bonding, then we mine as well call animals in the wild fraternity's and sorority's. Of course this can not in any way serve as a complete generalization of the entire greek thing.
Many groups serve the community as well as a way to better ones self.
However in groups such as the ones discussed, a rape may occur out of pure acceptance of sex being the sole object of ones mind. If the boys or girls encourage it in daily doses, then it will only make the chance of date rape more likely to occur. A man or woman does not understand the word no, like a child that has never been disciplined if it is taught another way as a sort of way of life. The point I'm trying to make would be one of complete unacceptance of a glorification of sex. I might sound like a total tool by stating this opinion, but I live in the real world and grew up in Chicago, dealing with cases such as these since I was thirteen.
