Interesting, but CAGW seems to be WAY more controversial.
In the case of Catastrophic Anthropogenic Global Warming (climate change), the controversy may stem from the fact that it’s all made up bullsquat advanced and maintained by humanity haters and their useful idiots.
In the case of Citizens Against Government Waste, its due to the fact that there’s some old school bleeding that needs be done.
And for Cultural Alliance of Greater Washington (Washington, DC), same as for Citizens Against Government Waste.
