I think even a better question would be: What is considered obscene? Back in the 70's, nobody seemed to be concerned with AOR stations playing an unedited copy of Who Are You, by The Who, yet occasionally a DJ is fired for accidentally letting a swear word slip, or for saying something defending gay people.
Given today's landscape of huge numbers getting their news and information from completely un-edited, many times anomalous sources, I hope the Commission continues to have obscenity cases thrown out of court.
Personally, I find examples of something like right-wing talk show host's advocating, let alone suggesting, that another public figure be assassinated, FAR more offensive and dangerous than an occasional F-bomb. But of course, that's called 'satire', or somehow a First Amendment right, when it suits the narrative.
