I wouldn't call what he said stupid. Whoever this person is has one heck of a sense of humor. I will defend the poster because he and I have the same type of sense of humor. Sometimes you just have to laugh and not take yourself to seriously. I am certain the poster knew of the contributions made by black people in aviation and other areas as well, but pointing that out before making a joke like that loses it's comedic value.
In my opinion, he said what others were thinking but didn't have the guts to say it. I know, some have more class, yada,yada... Chris Rock made millions from jokes like these. I would have made the same joke, but he beat me too it. I bet that both black people on this board laughed when they read that. He is not insensitive, classless, tasteless or whatever. He is funny. Don't take life so seriously; take time to laugh at yourself as well as others. Life is too short to be PC and not have a sense of humor.
