I’m not an expert on this topic. Heck, I’m not even an amateur. All I can say is that DNA testing is still in its infancy as a science or perhaps it is adolescent now. I don’t plan on getting tested until these companies get to the adult stage. If you DO decide to get tested, take your results with a grain of salt. Here is more on the topic-the comments are informative, as well.
Oh and even if I found out I had some little smattering of “American Indian” or whatnot, I would disclose this to my friends but I would still advocate for the future of White people. Why not? A lack of racial purity has never caused Obama to hold back his pro-Black sentiments has it?
