Weapon 3
Weapon 3 of the science deniers is to deny the credibility of the scientists. 2b will have laid the groundwork. All that's needed then is to suggest that the scientists are working for some evil enterprise. (Big Pharma is good, because that one is, to say the least, a bit too plausible. But the government is always there as Aunt Sally if needed). It becomes beautifully circular, self defining and impervious at that point. Any further scientist who supports the research is obviously in on the conspiracy - otherwise they wouldn't be confirming the research, because everyone knows it's a fake..Anyone who questions the reason (why would they go to to all that trouble and risk to fake the moon landings?) is just a dupe. Unless they are in on it, of course.
