I was just thinking about where ideas like his come from, & of course you know as well as I do that millions of people think like that even though they keep it to themselves for the most part.

That's because 'survival of the fittest' ideas became discredited after the world saw what had happened to the Jews in Germany during WW2.

Just because the elites stop believing something doesn't mean the idea has died out. On the contrary it's still there in the minds of many.

That's the hypocritical aspect of the reaction to his statements, which is all of a piece with the refusal to connect them to environmentalism, even though he said that was his motivation.

Anyway, if you're interested.
