I actually didn't see your comment on this point, but I'm happy to reply. That is a accurate description of Japan's demography. So what? The case for a limit on immigration doesn't only apply to Japan for that reason. Nor does your comment respond to my main point, which is that Japan doesn't have a homegrown Muslim terrorism problem
because of its immigration policy. Sweden is also racially homogenous, but has Muslim terrorism problems that Japan does not. Surely increased diversity is not worth
skyrocketing rates of rape?
In any case, a racially diverse country would be no different. America has been racially diverse for all of its history, but homegrown Muslim terrorism has not been a problem here, until now.
Your view is that any and all Muslims (in fact, any and all
anybody) should be allowed to immigrate to the US. Right?
