Fuck it, I'll play Devil's Advocate:
The point he makes about only white western nations being pressured to embrace cultural and ethnic diversity, while many other ethnically homogeneous countries - let's say India - far from facing such calls are actually celebrated as and protected from intrusion, makes for an interesting talking point.
Contrast for example, Bollywood Cinema to Hollywood Cinema - which of these is being lambasted more often for a lack of broader cultural representation and which is actually more guilty of lacking ethnic diversity among it's cast and crew?
I would say that generally, Western nations are a lot wealthier and have more job opportunities for people that promote immigration. As a result, the bar is higher for the US to clear to integrate those immigrants.
If India became the number 1 economy in the world that everyone wanted to immigrate to, then I imagine that with enough time, a similar standard would be set for them. I have been to India for work. It's a friendly country with a rich culture, but I could never imagine immigrating there and can't imagine their immigration application rate is comparable to the US.
