There are only two foreign nationals that I know of playing for SA. If you are thinking of Duncan being from the Virgin Islands, their full name is the US Virgin Islands. I'll give you a moment for that to sink in.
Anyway, why would Tony Parker's being from France make him more likely to convert to Islam than any American born black man?
Not one member of San Antonio is anything less than a gracious gentleman, which, in professional sports, is as rare as a white raven. Is it too much to ask that you judge them by their actions and words than by where they are from?
Yes, I know all about the "US" Virgin Islands. However, although he is an American citizen that does not make him an AMERICAN. There is a huge difference between the two.
Don't EVER go to the US Virgin Islands and tell one of the natives that he is an American. He'll kill you.
Now, YOU let THAT sink in. :-)
