>> any regulation there would risk violating the 1st amendment. Perhaps, but its a risk the US took for decades (1938 - 1985) and the political climate was less divisive during that period. You can't say "nothing can be done" when things can and have been done that we don't do anymore. https://en.wikipedia.org/wiki/FCC_fairness_doctrine

I am not saying something like that is a good idea. I am saying that to throw your hands up and say nothing can be done is not accurate. A lot of times people say you can't regulate a thing because you can't regulate every possible instance. But by that logic we shouldn't have stop signs because people run through them everyday. Yet stop signs are important.
