Global warming (excuse me, "climate change") is the new religion of the American and World Left, complete with its own messiah in the form of Al Gore, the self-proclaimed "inventor of the Internet." They love their messiah and his message of industrial-hate so much that they gave him a Nobel Prize and Oscar for his farcical AGW film and faithful advocacy.
It's so much of a religion that Al "Gore-Christ" tells us that "the time for debate is over." But any REAL scientist will tell you that science never stops debating and searching; in science, debate is never over, especially when it comes to certain questionable theories--like "man-made" climate change, for example. What does the Gore-Christ really want? He wants what any politician wants--power, and the best way to leverage power is to create more social bureaucracy (the "Government" wants to save you from yourself because you're too stupid to know any better).
Gore and his followers want "debate to be over" so that you'll shut up and goose-step through the public square, yelling at other non-compliant people driving SUVs and eating red meat. They want you proclaiming all capitalist humans as the murderers of Mother Nature.
So when CBS decides to air a show on climate change (that makes no mention of 400 worldwide scientists who disagree with or question manmade climate change as it is currently propagated), CBS pulls out the ol' Holocaust-denier comparison:
“Every time you address the Holocaust, you don’t bring somebody in that says it didn’t happen. And we’re at that stage now. We have Holocaust deniers; we have climate change deniers. And to be honest, I don’t think there’s a great deal of difference.” That was the blunt assessment of Bill McGuire, an earth sciences professor, on ABC’s Aug. 30, 2006, “20/20.”It's much easier to shut us climate change deniers down by just comparing us to really awful people in history, like those who say the Holocaust never happened (basically calling us Nazis); that will keep us quiet and in our place, so that they can continue to turn the sheep out there into climate zombies who chant, "Al Gore-Christ! Al Gore-Christ!"
