The link to the letter is pretty good stuff.
I always thought it was odd that christians would be against doing anything about "global climate change" (true or not). I thought it had something to do with Revelations and that they see global warming as a precursor to the return of little baby jesus. But now we see that the real reason is it will divert resources away from the inquisition of homosexuals.

It's interesting how Christians can deny a moral debt for the crielties inflicted and the atrocitied performed in the name of Jesus while at the same time holding grudges aganst others for deeds long past and also maintining that all of humanity bears the guilt for something done at the beginning of time (i.e., "original sin")
