  My personal experience of more than 60 years tells me your vision of all humanity being mixed-race will never happen.  In most instances your experience adds wisdom but, here, your age is a drawback to understanding the state of American society. As someone of the younger generation, I understand how we think. It's true that if we all had a background similar to yours, it would be silly for me to predict this vision, but our generation is altered in a way you won't be able to grasp. In the East/West coast parts of America, among the younger generation, dating between the races is a nonchalant matter.  Us real Americans and good folks in the South and Mid-West couldn't care less about you perverts in California and New England anyhow. Most Midwesterners and Southerners are really just wishing you'd fall into the sea already. So no worries mate. I live within an hour from Detroit and around here interracial couples literally get the evil eye from both White and Black people when they pass by. Oh and did I mention that my home state of Michigan is officially the most segregated state in America? I happen to take great pride in that too :D
