You must be joking. Or just trying to get a rise.
And anyway, maybe, coming from Africa (but how could you know if this were true?), I'm missing the American significance of this. Because it seems to be a really irrelevant thing to be concerned about. I hate to be the one to bust your bubble here, but coming from Africa is not all that incredible. After all, nearly 800 million people have managed this 'accomplishment'. And there really is nothing like an American coming to Africa for the first time, having had the benefits of a first world education and healthcare system all their lives, and saying that they are now 'home', when they have NO concept of what it's like to face the realities that most Africans deal with every day.
And as for your assertion that you are black, native (Native American, I'm assuming, but considering your line of reasoning it seems lax of you not to specify) and Irish:
1. How do we know? I mean, just because you say it on the internet doesn't make it true, no?
2. Why would we care? What's the point of this argument?
Okay, I'm slinking back into my box now (anticipating the Wrath to follow...)
