@flo Yes, there is an endless list of things that we should all not do, and likewise and endless list of that what talk show hosts and newscasters shouldn’t do and an endless list of things that their employers shouldn’t compel them to do, and among those things would be, for example, biting the heads off of live baby lemurs, masturbating on the set, delivering the news, for newscasters or conducting interviews with their guests, for talk show hosts, entirely in pig latin and throwing human or animal feces at the camera operators, or anyone else for that matter.
Also, the professional standards for newscasters, who are journalists of a sort are entirely different than those for talk show hosts, who are basically entertainers, not journalists, and don’t even pretend to be.
I answered the question as best I could but it is too vague for me.
The question may not entirely be about what you’re getting at but I can’t answer it without more information, again, sorry.
