Why was dancing banned in "Footloose"?

There was a real town in Oklahoma that banned dancing in 1898 to control drinking and kept that ban for 82 years until some high schoolers fought to hold a prom in 1980. Screenwriter Dean Pitchford traveled there to research their story but decided to dial up the drama and gave us a grieving father instead of an ancient temperance law. And technically, the kids in the movie never even overturned the ban. Their prom was held in a grain mill just over the county line, which is exactly the kind of thing a big-city boy would pull off to annoy a town council.
