I have some pity for you, Chief One-Drop. I can only imagine the ordeal of you trying to go to a local casino to cash in on your inheritance and them flipping you the pair of poker chips you're due.
Of course I consider people from the U.S. "Americans." It's just that Canadians, Mexicans, and Venezuelans are just as "American," as they're all residents of America. While you screech and wail that this is wrong, you never actually disprove it with argument.
Aside from the fact that they're all American Indians,
you never specifically said the bolded portion, but it's an application of your belief. Firstly, you moronically imply that Mexico is in Central America, despite the fact that it is not. Then
you continue to insist that there are differences between American Indians based on national divisions. While there are indeed genetic differences based on geographical location, it's idiotic to imply that "Central and South American Indians" are somehow a homogenous group just as "North American Indians" are. The Indians of the U.S. Southwest, for example, are more closely related to the Indians of Northern Mexico than the Indians of Northern Mexico are related to those of southern Mexico.
