Of course the entire point of this article (and others like it) is to give right-wingers are an excuse to feel superior to "those hypocrites on the left". So let's not get too self-congratulatory about our own ethical honesty, shall we? It amounts to the same thing in the end.
The thing is, there is a difficult problem to be solved. Finger-pointing and denunciations aren't going to solve it. Expecting the bulk of humanity to spontaneously reduce their carbon footprint -- simply because it's the right thing to do -- is clearly not a viable strategy either. If we really want to solve this problem, it will take hard work, determination, and ingenuity, of both the technical and political varieties. And it will take seeing other people as thr fallable-but-well-meaning human beings they generally are, not as cartoon villains to fear or paper targets to take pot-shots at.
A little more constructive dialog, and a little less demagoguery, please. I'll start: a revenue-neutral carbon tax would be a good way to tilt the market away from carbon usage without restricting it to any pre-ordained solutions that might or might not be sufficient.
