Are you a racist if you prefer to live in a mono-ethnic society?

[politicus]

I have noticed that most posters consider any defence of ethnic homogenity to be racist. Given that most of you are from highly multiethnic USA with a troubled racial history that's not surprising.

But given that many Asian and European societies are historically monoethnic or almost monoethnic I personally don't think that's true. You can be against immigration of people from other ethnic groups without necessarily having any feeling of racial superiority or prejudices of people from a different background.

Fx. South Korea is about 99,98% Korean and all Koreans I have met define their national identity as ethnically based and prefer their country to stay that way. Does that make them racist?
