Besides the absolutely dumb idea of a flat Earth and the dismissal of pretty much everything produced by the space program of a dozen countries, there’s something really interesting going on here.

It also shows a worrying connection between populism and disbelief in science. I’m all for emotions, but to demolish science in such a way brings thoughts of dystopia to my mind.
