Global warming hypotheses are very recent and are not well established and accepted science. No doubt the DIMs are politicizing it. I'm with you there.
OTOH, some on the right seem to want to politicize the Theory of Evolution. The Theory of Evolution is 150 years old and it is well established and accepted science supported by 99+% of the scientific community based on converging scientific evidence and investigation in many areas. But because some think is conflicts with their religious beliefs it, it is attacked with the most vile and vicious accusations imaginable.
We are just rerunning the same discussions I have seen innumerable times here on FR. There's no point continuing it. Hopefully, we have enough common ground to hold together a majority conservative coalition.
Just like the "science" of global warming, the "science" of the theory of evolution started out as a political issue, still is, and always will be as long as there is a God in Heaven and religious people on Earth. You people should quit lying to yourselves. It's a political issue!
