That is not thinking. That is just superficial racism on your part. All of my life I have visited and enjoyed Minnesota culture which has a very strong Scandanavian influence. It is not like other places in America, in that regard. Somalians are very different culturally in thousands of ways. They also settled a big group of boys from Liberia, I think, who had been child soldiers. They were acting out in school in ways their teachers couldn't understand. This was because they had been at war, not because they were black. I also always hear mention of Hmong.
So, you take a culture that is cohesive and make it multicultural. Who has the right to do that? Certainly not someone who can't see anything but skin color. That is so shallow, it should be embarassed to speak.
