If I am gulity of knowing nothing about the politics of it, then you are equally gulity of knowing nothing of the science of it. Untill you understand the science behind climate change, you can add nothing to the conversation of how to deal with it. If you simply wish to reduce this debate to another left/right culture war issue, you do not only do your self a great diservice, but us all.
Yes, many different political groups have done the very same, however, this is something that transcends simple partisan politics, as we are equally dependant on the natural world for our continued existance.
Though, I do agree with you the sole focus on CO2 emissions is a very surface-oriented view point, and doesn't really add anything helpful. And the American left in particular has a very strange relationship with enviromental issues, so I don't think they are any better.
