Replying to High School bans dancing

My high school just banned grinding/freak-dancing from school dances the day before the biggest school dance of the year. They said if they catch anyone doing it the dance will be immediately canceled. Dances at my school have been sub par for a while, and student government has been working on making them better. The administration's reasoning for banning grinding is a poll we took over a year ago, where a supposed 40% of the school said that grinding made them uncomfortable, and they were bing excluded. Senior prom is 100% funded by the proceeds of the next dance, and no one is going to go so we are boned.

Anyone else dealt with similar problems at their school?
