I've heard exactly this argument from a middle school science teacher friend of mine — when asked, though, he wouldn't volunteer to go first
/Professor Bill McGuire is a well-known vulcanologist and climate scientist who doesn't care much for humanity. …. Ooopsie. McGuire deleted the tweet a few hours later but had no regrets. The trouble is, we just don't understand how brilliant he is.
As I said, I have a friend who remains a friend so long as we don’t touch on politics, but he’s given to grand pronouncements of what he perceives as his field of expertise, global warming. One day recently, while he was spouting some truly misinformed nonsense about how solar energy would save the world, he pronounced that the maximum population the world could support was one billion (a figure often cited by expert depopulators like Bill Gates). “How will that be achieved?” asked I; “what will you do with the surplus 6 billion?”. “War and disease will do it”, he explained.
So this jolly, jovial fatman, beloved teacher and ardent Democrat, hates humanity just as thoroughly as the rest of his peers; that’s not surprising, but it is a warning of what they have in mind for us.
