Okay, so we can agree that they're racist--now what. Or, so what? We can't change anyone's racist mind by pointing it out to them? So, what's the point? If they were anti-semitic, would it be worth pointing that out? Is it worth pointing out to the Saudis that they are anti-women in terms of human rights or that their practice of not permitting religious freedom is discriminatory? Should we have kept quiet about apartheid? What's your point?
How many times do any of these things need to be pointed out? I'm sure they all know what their attitudes are and that it's a problem for others in the world. As long as they're not terrorists, what do you hope to gain by pointing it out? Apartheid? You mean the evilness of having the minority population run things? Maybe we should end apartheid in America. South Africa is in much better shape now, aren't they?
I really don't know what any of you handwringers expect to accomplish by worrying about racism from people who don't live near you. The Japanese are not infringing on your quality of life.
