Steyn touches on something that I’ve often thought about. The only places where multiculturalism is taken seriously, and taking place, is in the Western nations. How’s multiculturalism coming along in China or India, or dozens of smaller nations? It’s not to any meaningful degree. Only the West has bought in to this nonsense, but other cultures are happy to use it to their advantage when criticizing the West, or when they want to immigrate to the West.
“Only the West has bought in to this nonsense...” Only the liberals in the West, you mean.
Digressing a little... Liberals depend on their ability to manipulate groups rather than individuals, so populations have to be broken down. And “culture” is one way. Other ways are skin color, “sexual preference”, age, wealth, age, etc...
In other words, the liberals would love nothing more than to have groups (in this case, cultures) of people migrate to America rather than “individuals.”
To me this is what it’s about.
