Dances, Debates and Ann Gray

Imagine you are in a public place like the quad outside the library or in one of your college's buildings just having a nice time. It's possible that you are standing around hanging with friends. You could also be alone. Suddenly a man you have never met before gets behind you and starts pressing his pelvis against you repeatedly. This seems inherently wrong, no? It can be classified as sexual assault or at least harassment, especially if you tell him to back off and then he just comes back a few minutes later to try again. There is definitely something perverse about this situation, and I would hope you all would agree.
Now my question is: Why does adding music to this situation make it socially acceptable? Friends, I am talking about college dances. These profoundly confusing events are quite different from high school in one aspect. In high school, if you choose to get hot and heavy on the dance floor, it is with someone you know. It is consensual. It is still creepy, but I digress. Here at college, males just prowl through the masses of dancing students, single out females, and then exert their will upon them.

This issue has forced females who attend dances to create a system of defense. The girls must dance in groups together, staying close to one another in order to defend themselves against the men. It's almost like how animals move in a pack to protect themselves against their predators. In the female's system of protection seen at dances, they dance fairly close together, and it often could be seen as intimate if it weren't for the fact that the reason they do this is  the "stalking" males cannot.
