Yes...we are American......but not American LIKE YOU. That is what you keep forgetting. Just because we are all American does not mean we have a lot in common. A person growing up on 6 mile in Detroit is not going to have a lot in common with a person who grows up Casper, Wyoming. However, you do make a good point in separating black culture from "African culture". Black culture....and all its perceived issues and problems, was created in America as a reaction to or in emulation of parts of white culture. Its a byproduct of AMERICAN racism.
It's actually a product of the monetary policy.
I'm of Cherokee origin, myself. But I had a single European ancestor that came over in 1626 who became part of the original, pre-American colonies. I guess they mated with the natives there inwhat later became Virginia, over time. In my line, they apparantly kept doing it. Turns out that it's the female side that passes on the genes. My grandmother looked darned near full blood, nose and everything. Her mom was of primary Cherokee origin. As was her grandmother. That's likely why it's so prominent in me. Any European I have in me is likely since diluted over time.
I don't particularly consider myself caucasian. Not really. But, I have to consider myself American. I'm a native, for the most part.
It's kind of why I get to quietly chuckling when my fellow black American peers refer to everyone as "you whites" Odd, thats it's just assumed so arbitrarily.
