If you are a native of Africa does that automatically make you black?

First of all if you are born in America and you are black you are american same for whites and hispanics. And why do we need to use all of that stuff if you are black you are black if you are spanish you are hispanic same as whites. But like I said if you are born here in the U.S you are American. And so many people are mixed now so pretty soon in a couple of years so many more will be different races which I find fine nothing wrong with thing's are changing:)
