Because, as Dr. King said, it would be a good thing if the whole country did it. But the Power Structure sees color, and so do millions of stupid white people who get one vote each, so we have to. It’s one of those things we can’t escape, like government and bondage to our bowels.
ETA: Thank to several helpful comments, I realize this should have been something like “I wish I lived in a world where I didn’t have to see color, where we didn’t have that particular element of collectivist politics that makes many people suffer and gives the rest of us another civic duty.”
