MilfordHusky did, indeed, enter a minefield but also is taking a stairway to heaven. Race shouldn't matter--and may we all live long enough for that to be the case. But one way to make it not matter is to celebrate the times when it doesn't.
Of course, we're all "multi-racial kids", not only because of the surprises most folks have when they do "23 and Me", but because the modern notion of race is a late 18th/early 19th Century construction. Anyone who studies the ancient world knows that whatever passed for "race" was entirely plastic and flexible and nothing like the narrowly-constructed categories that formed just two centuries ago--largely as a result of the anxiety of inclusion/exclusion with the birth of the nation state and capitalism's exploitation of chattel slavery.
While we should all strive to be color-blind (racially, not optically), we can also realize that celebrating the success of a program/environment/people, etc. to make everyone feel comfortable regardless of apparent physical differences is a pretty neat accomplishment (to say the least).
