>[homogenous Japanese population] is the farthest possible away you can get from [unrestricted immigration from the southern hemisphere].

Why yes, indeed, it is!

This is an absurd argument considering that American zoning has been exceptionally successful at segregating black people into their own separate communities. You have homogenous American neighborhoods and cities. When you are blaming someone else in this way you are not only admitting defeat but you are also an asshole.

American neighborhoods are homogeneous, and you can see the result when you walk between them.

Ah, racism. Long time no see.

I'd certainly be interested in how racism within japan affects the housing market there, especially considering the racial bent behind this Canadian policy

"Long time no see" is a racist mockery of Chinese immigrant broken English.
