Never answer a question with a question.

I'll tell you what does not define a race....the quantity of melanin in one's epidermis as is so commonly believed.

Both Einstein and Obama's Luo father share the same Haplogroup E 1 b 1b1-M35.1.

The Fitzpatrick dermatological scale from 1-6 ( light to dark) is related to the response of the epidermis to UV light and is not a race defining scale.

The epidermis of Hitler's ubermenschen Aryan race ranges from I to IV ( German-Iranians).

Most of those  white suprematists who regard themselves as being members of the Hitler's National Socialist superior race, aren't.

For my part I'm definitely untermenschen.

Still no answer to the question posed.
