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.
