Monday on TV: Howard Stern holds the moral high ground over the Parents Television Council

Howard Stern holds the moral high ground right now over the Parents Television Council - which gives you some idea what to think about the PTC.

Stern, whose radio antics used to make headlines until he left broadcast for satellite, is joining the judging panel of America's Got Talent, which returns tonight (7 p.m., NBC/Ch. 5).

The PTC is calling for a boycott of the show. Which they haven't seen yet.

The reasoning is that because Stern is rude and crude on his radio show, he'll be rude and crude on "America's Got Talent."

By that logic, we should boycott every G-rated movie that stars an actor who has ever been in an R-rated movie.

I don't know how crude Stern will be on "AGT." I haven't seen the show yet. And I don't review shows I haven't seen. Because that would be unethical.

If the PTC wants to protest something that has actually happened, that's one thing. But unless they have a functioning crystal ball, protesting something they think might happen is a highly unethical thing to do.
