So, anyway, what's the deal with "Barack"? It isn't a name and it isn't a proper word.
It's not even an ethnic black name, since it doesn't have any apostrophes and it only has one capital letter.
Now "barracks" makes a really stupid name, but it's a perfectly good word and I suppose the singular form would be "barrack", with two Rs.
I think "Barack" is kind of like "Dwyane" Wade, or "hippywife", where there was a degree of ignorance at its origin that prevented proper spelling.
