Haggard uses his position to promote a phony science espoused by world government Socialists. Evangelicals who push global warming must be opposed. Period.
I agree that the idea of global warming must be opposed (not just for opposition's sake, but with facts, as I'm sure you agree). I'm not sure that "rotting in hell" is a proper consequence for pushing pseudo-science on others. Now, having homosexual affairs and snorting meth? That might qualify.
