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.
