Simply having a cup of coffee in a restaurant could lead two people into having sex. Im sure that in your youthful days, your peers were danicng in sexual ways as well. We tend to forget that people have danced like this when people found out they had legs and could dance. True, it may be inappropiate for a group of pepople to freak dance in the middle of the hallway. And how in the world can you compare a male's motive in freak dancing compared to that of a rapist.
Rape is too serious an issue to be compared to a dance with a sexual nature.
I mean I doubt a person will rape a girl while dancing at the school dance. Rape may not always be avoidable, but freak dancing can be put to a halt when the person dancing is ready to stop.
