I agree.
That said, I make a distinction between the Flat Earth theorists of olden times versus today's theorists - for example, Climate Changers. Those who expounded the Flat Earth theory lacked much (if any) evidence to the contrary, and scant evidence with which to postulate an alternative theory. So, the ancients' Flat Earth theory can be viewed as honestly-derived but wrong, and its' proponents (with the benefit of hindsight) as being dumb and/or ignorant.
Today's Climate Change proponants, being neither dumb nor ignorant, are forced to carefully pick and choose which evidentiary support to flaunt, and which to conceal, ignore and/or discard.
Of course, Climate Changers' use of cherry-picked evidence only serves to bolster their detractors' assertion that "Climate Change" is only a ruse - based on demonstrably false or intentionally misleading premises - to accomplish an undisclosed, more sinister agenda (e.g. World Economic Forum agenda).
Mark Twain famously wrote, there are three types of falsehoods: lies, damn lies and statistics. And Gen. MacArthur observed when describing President Franklin Roosevelt, "He was a man who would never tell the truth when a lie would serve just as well." So we find ourselves, again, confronted by those who lie by choice and preference. Twain tied a bow on this when he observed, "History may not repeat itself, but it often rhymes."
Liars gonna lie. Some learn how at home, but most learn in law school and then refine their craft in public service.
