Ain't immigration and diversity great? More and more I tend to think that homogeneous societies like Japan have a lot going for them.

Also, like Greece, Sweden, Norway, Denmark, Finnland, Switzerland, Germany, China, that is, most countries who insist on preserving their own native culture, tradition, histories, language, etc.

This news story has SUCH a familiar ring to it -- Los Angeles, black and Hispanic gangs.
Everybody loses with multiculturalism, even, to some extent in multi-ethnic/racial/religious societies where the dominant culture is under CONSTANT attack, via 1. worship of other cultures/ethnicities/races/religions and 2. self-hatred, from its own members.
See America, Euro-Americans and Chrisitanity.

Germany and Scandanavia are overrun with Muslims and Multiculturalists. What gives you the idea that they "preserve their culture."

America does NOT have a "blood and soil" culture as they do in Japan. It never has.
