I'm thinkin' he just watched the movie, especially with the "Red Tails"/movie-title references. I never heard any of the few I met from that fine unit, proudly (properly so) speak of themselves as other than Tuskegee Airmen.
To the points at hand though: You're posts are on the mark here. Those gentlemen indeed weren't any "social experiment", but were instead, yet another in the long line of segregated units in history, which does nothing to advance the thread's originator's fantasies and agendas.
The bottom line is that defending America or projecting power against our enemies necessarily transcends personal interests and egos. The important thing isn't to fret over which fingernail wants to be painted how or what color, but how best to form our fingers into a lethal fist. Only the most self-obsessed, infantile narcicissts would differ there. The only real question we should ask is that of how we best equip ourselves to do so when needed....Period!
