In the mini-series “V” (the original back in the ‘80s), earth scientists start to suspect the aliens aren't as benevolent as they're letting on, and start speaking out against them. The aliens’ response is to go about discrediting the scientists with the public, and it works.
Life imitates art.
Republicans, beholden more than Democrats to big, polluting corporations are busily following this script. And corporations, who fear loss of profits far more than loss of jobs or increased costs they will just pass on to the consumer if climate change legislation passes – despite the fact that environmental laws they opposed in the past haven't had this effect – have been busily pulling their strings.
Look back a ways and you'll see a pattern. Just in case you don’t remember, this is a repeat from the 1970s when the Clean Water Act and Clean air Act were being debated. It’s a repeat of the 1990s when acid rain legislation was being debated. But it’s being done with a new twist. Don’t just attack the science, attack the scientists. They have an agenda. They’re really leftists bent on destroying capitalism.
Look on the websites of these ‘concerned citizens’ groups’ (with deliberately misleading names like the American Council on Science and Health) and see who’s really backing them. And understand you’re seeing a dog and pony show.
