People as a whole develop. Parents and grade schools can't control the way they used to. The 18-21 age range is so difficult in this society because on the one hand you may be treated as an adult, but on the other hand, you may be treated as a child. It is completely arbitrary. You can serve in the army, but you can't buy beer.
People come to college to find out who they are.
You may come here and decide you want to embrace a particular ethnic or religious identity. But it is the duty of the University to allow people to be free to choose, to examine, to explore for themselves. If you want to have this bonding in a university of this size, students must be allowed the option of doing it through fraternities and sororities. There are the costs and the problems, but it also gives young people the chance to develop lifelong friendships. I don't think so.
