No, no, no.
You see, slaves' descendants are dark skinned. Therefore, they absorb heat and keep North America cool. It's the whites who are evil, because their skin reflects the heat and light back and heats everything up.
This is another reason why we cannot permit drilling in ANWR. All the honkies headed up there, just by sun reflecting off their, will cause a local micro-warming that will melt the permafrost.
Oh, and in case you were wondering, that Kennewick Man business does prove that there was ONE strain of white man in North America at the time of the Indians. Where do you thing the Indians learned a nasty habit like smoking tobacco.
So that, my friends, was the contribution of the European to the Indian before Columbus and the Vikings. They were over in North America just long enough to teach the descent, hardworking native immigrants from Asia how to smoke. Then they died out. So really it wasn't the Indi...sorry, Native Americans...teaching the Europeans how to smoke tobacco, because (by definition) they could have done nothing bad. It was, rather, Native Americans reteaching whites the foul habits that the ancestors of the whites taught the Indians before dying out.
More and more science is proving all of this everyday.
He was here at least 3,000 years before the Indians.
