To those that know nothing of Biology here is a short explanation of skin color.

To those that know nothing of Biology here is a short explanation of skin color.
Melanin is a dark pigment in the skin that protects skin from the rays of the sun
The reason for it's presence is the process of natural selection.

Those that live in places with great amounts of sun exposure have genetically adapted to this sun, by producing more melanin to protect themselves from the sun's rays.
The more sun, the more melanin, the darker the skin tone.
That is it
That is the reason for the darker skin

It is in no way inferior
In fact it is superior
Superior for those living in areas with high levels of exposure to intense sunshine.
So White Supremacists do you get this simple explanation?

Humanity is one and the same, we are all the same with different skin tones.
God or Natural Selection has simply protected people from the sun.
