Since I don't prefer any race over another, a million people is just a million people. Since I am white, it would be easy to live with all whites. And at least I'd know that nobody I come in contact with hates me because of my race. Racial diversity can cause discrimination problems, but I like racial diversity. I don't need it, because there's millions of ways to be different than everybody else and to discriminate against people regardless of skin color, but I do think it's cool because it actually reflects reality and brings us together better on a global scale. We might have come from many different places, but we are all here right now.

I would approximate the racial breakdown in the area I grew up as approximately 1/3 White, 1/3 Asian and 1/3 Latino/a. And I'm used to it, and being in a predominantly white environment would be uncomfortable for me. I don't know how long that discomfort would last.
But around here the racial makeup of the block has most to do more with what zip code/ side of the freeway you live on, so there are lots of little pockets with greatly varying racial makeups. (I live in suburban sprawl- streets, streets everywhere, no stop in sight.)
When I was a sophomore in high school, my best friend (who is European-American) moved 15 miles away and started going to a different high school. One that was predominantly white (70-85%?). It *was* weird for her, and I definitely noticed it when I came to visit.
It would seem after a spell, slightly dull. Unobservant as I can be at times of my physical surroundings, it would take me a little time to place the homogeny, but eventually I would notice and mourn the repetition.
