Did you take a look at any of the photos on this thread? I used to go to some dances in the 60s and this stuff is way, way beyond anything I ever saw.
Live and let live means let humans acting like animals in rut take over not only the high school dances but the beaches and parks.
It’s about 3 fibers away from live sex in public.
slippery slope argument perhaps but there was some crazy dancing at my prom in 1989. It seems there are other more important things to worry about.
