You can't trace your lineage that far back; neither can I. The argument is not genealogical, it's culturo-historical, and deals with macro-history. That's why even though I don't know my great-great-great-n grandparents' names, I know they likely had topknots, wore saris, or had boiled leather shoes. Genealogy has very little to do with it, and "diaspora" usually involves the identity of an entire ethnicity as it disperses globally. The other point was the identity politics point, which you've proven indirectly: black people aren't get so much crap from ***theads like you that they need any advantage they can get; dressing sharply is one.
