Jon Stewart has always been in favor of constructive dialogue. This is what a lot of his humor is about. He often has guests on his show with whom he disagrees but is always respectful because that's what you do in a decent conversation. You avoid name-calling
and shouting.

I think his march is a good model for what America needs to be. He may hold positions with which I would not always agree but he is a great humorist and lightens up the tension between ideological clashes this way. Colbert essentially does the same thing in a "devil's advocate" role. Their feud is great fun and you can tell that they really are pretty much on the same page politically.

Their point is well-taken. People have forgotten how to converse with one another. They trumpet their points-of-view as they would brandish a weapon. There are many Americans who have not made up their minds ideologically and they need to be regarded and respected. This is where Stewart and Colbert are doing a great service to our country.
