In addition, something to explore is Vit. D deficiency. Darker skinned people living in Northern latitudes are not as efficient at producing Vit. D from sun exposure as lighter skinned people.
That can somehow be construed by the Left as being racist.

Indeed, and here in the NE you should take Vitamin D in the Winter no matter what color your skin is. And it is character, not color, that matters, while as one who has suffered 2nd burns on much of my Scottish/Irish body (as a teen) just by trying to be like my friends of Italian descent (about 5 hours at the beach) then I favor a darker shade at least.
