I think you should actually look at what the Koch's actually believe and what they fund. They've been on the right side of history for a long time, and in fact the much hated David Koch took a stand and ran as VP of the libertarian party in the early 80s with key planks of his platform being drug legalization and the legalization of gay marriage. The Kochs also recently funded with Soros a think tank in washington dc to help promote the idea of peace and stop the endless wars the US is involved in. As far as I know David Koch didn't deny global warming, but strongly disagreed with the conventional ideas of how to combat it and the risks that it poses. There are many people who think that there are better ways to address it. For instance, addressing 3rd world poverty and increases the wealth of the world will increase the rate of climate change, but it will also benefit those suffering substantially and enable thier children (who are richer) to better handle it. I don't necessarily endorse or agree with his views, but I feel they're often mistated for political reasons.
