However, America has always had obscenity laws, blue laws, and community standards until very recently

Those were typically engaged at the state and/or local level and were fairly narrowly tailored. A blanket ban on rap, for example, would fail such a test, because you would be banning Lauren Hill along with 2 Live Crew. You would need to examine specific content from specific performers (I won't call them artists) and not a genre.

I concur.

That I definitely agree with too...
