Techno-Hypocrisy
At the top I don't think the propagators of these idiocies are sincere, but they are leveraging the last 40+ years demolition of our education system to get hoi polloi believing the most amazing and destructive bullshit.
If I could arrange the universe in a right and just way, I would force these villains to spread their ideas at the same scientific and technological level as the ideas themselves. No smartphone or Internet for the deniers of science: quills and parchment only.
