It is not that I haven't read the article. But what you are making a fuss about is none: wether the first slaves in the colonies were African or American or African American or Aliens or whatnot. Who, recognizing what slavery is, can care? That is my point as a human being: some things does not matter at all whereas other things do on any occasion. Did you get me now?

You in the USA are both blessed and cursed: you are a human society as colourful as God meant it to be and you are puzzled by all its human invented problems and fighting about them. If you consolidate of what you are, a society of free human beings, all with equal rights and duties, helping each other to get along, you could be the shining city on the hill.
