Truth telling versus polite dismassal
My dad was in politics. People would come up to him all the time with crack-pot (but seemingly well researched) theories. "Cell phones are going to give us cancer",. "TV is ruining my kids eyes", "Despite the current glut, we're on the verge of a shortage of natural gas".
A nice way to get rid of such people is to say "That's an interesting viewpoint, but I don't think the public is ready to accept it".
I can imagine Chris Nedler and Art Berman soliciting such a response. A lot.
