That's pretty much my take on the Kochs as well. They seem to contribute to things they believe in, which incidentally includes public radio stations and hospitals [0]. You may not like their politics--and many do not--but so far everything I have read or heard about them supports the notion they are sincere in their beliefs.

The problem is not so much the Kochs as the fact that we've permitted a political system to arise in the US that allows a disproportionate amount of wealth to flow to a relatively small number of people and to allow those lucky few an outsized influence on the evolution of said system. Those two things are not unconnected.
