The world has changed and its not obscenity that offends anymore, its racial slurs and the like that would get the most attention. Its also harder for most people to do honestly because its not the subjects you cover, but what you say about them that will offend. That kills the " deal with the facts of life frankly and honestly" idea - it would only work if your honest view is one that people will find objectionable - but then so will most publishers.
This reminds me of Harrison Butker’s commencement speech at Benedictine College a couple of weeks ago.
This was a speech by a fairly obscure guy (he is a place kicker) at a fairly obscure college. But because he said something our culture considers obscene, his speech was on the front page of all the news sites and talked about on Twitter.
Normally, maybe a few hundred people would have heard his speech. Now likely millions of people have at least heard a portion of his speech.
