Dammit, I wanted to say something about this, but I was beaten by 14 hours. But I'm still gonna anyway!
Yeah, there's no "Native Americans" in the same sense there are no native Europeans, no native Asians, and no native Australians (talking about the Aborigenies here). All of mankind originated in Africa and any group that is known for being from some other continent were descendants of immigrants. I thought this was common knowledge, and assuming tsar did know this, what was the point in pointing out "well actually, Native Americans immigrated here" without also mentioning the same of all non-African races / continents?
