I believe that reasonable people don't need to be told what is bad for them and greater society. We tend to self-police on these things. Some simply cannot or will not act sensibly. In earlier societies they were dealt with directly and not let go to do it over and over until they kill someone (again). My complaint is with all the things we are not allowed to do, even though harmless to others. Freedom much?
I have to admit, the thought of people square dancing on a moving railroad turntable sounds like cheap, homegrown amusement. Or did I miss your meaning there?
