Other than needing an insulin injection after that sugary video, so what?
Do those criticizing the video know the lack of black women in it is due to Alpha Phi discrimination rather than black women at UA self-segregating? I can't speak for AL, but blacktivists at Berserkeley demanded and got their own all-black dorms 10 or 20 (or 30?) years ago.
As fl said, there's about as much evidence for discriminating against redheads as there is for discrimination against blacks (and Alpha Phi redheads may have chosen not to appear, not wanting to risk sunburn from wearing shorts and/or bikinis out in the sun).
