Trump has made the conspiracy cultists bold, and it's now 100% conspiracy nuttery from the deniers. They no longer see the need to pretend they care about the science. This is the Trump post-truth world, and the cultists believe reality is whatever the cult says it is.
Rational people see things otherwise, of course. Which is why it's so difficult to find a conservative/libertarian scientist in any field. Superstition and science just don't mix.
Carl Sagan called it, in 1995. It just happened quicker than he imagined.
“I have a foreboding of an America in my children's or grandchildren's time -- when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness...
The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance”

The Demon-Haunted World: Science as a Candle in the Dark
Sagan's baloney detection kit comes in handy here. He says to check if something is falsifiable, and apply Occam's Razor, and see if they depend on logical fallacies. Denialism fails all those tests, while mainstream climate science passes with flying colors.
If any deniers disagree, they should answer the one question they've always run from, which is "What data would falsify the theory of denialism"?
