Simpatico with a lot of the other content in this thread, but more direct. At least he isn't talking about angry blacks with a chip on their shoulder rejecting the white wisdom of the west. All of the Idiocracy mentions aren't very far away from this guy in essence, though.

It's unfortunate that people don't want to talk about the elephant in the room because it's too politically incorrect to.

All you have is name calling. He’s right. Low IQ populations can’t maintain complex power infrastructure.

The real question would be "what if he's right".

Imagine there was an island discovered with some sort of transitional, Homo Erectus style people. Let's say they can't, for organic reasons, exceed IQ 50 - can speak, wildly efficient in hunting and foraging, can't figure out 3rd grade maths, can't learn letters, can't understand how seeds work.

What would be a reasonable policy towards such people?

If you find out the answer, let Australia know.
