Not nearly as many Americans as there were when I was growing up in the 1940s and '50s thank God. The MSM only cares when they can use race baiting to goad minorities into voting against Republicans, and to accuse conservatives of being racists.
Skin pigmentation does not always define a person's racial background, and it doesn't matter anyway except for the much higher vulnerability of white skin to skin cancer. Skin color is most certainly not an indicator of the character or moral integrity of an individual of any race or skin color. I would be quite happy for Mr. Jindall to represent me in Congress or in the Governor's mansion if I lived in LA, something I definitely can't say for millions of lily white Caucasian liberals.
Dark skin in a low sunshine area gives an increased vulnerability to rickets. Skin color is a balancing act.
