Heard a few minutes of an NPR discussion program this morning, the introduction to their segment on the protests in Wisconsin. It's good that they are covering it at all, but while I didn't listen to it, the announced guest list was fairly typical of these things. The first was a historian of social movements. The second was some hack from Cato. This is fairly typical, with the liberalish side of things* being presented by someone non-political, who is then "balanced" by a movement conservative.
*Not having listened it may not have been liberalish at all, but obviously person A needed to be balanced by the right wing hack, according to the powers that be.
