I think that a mexican that goes to school in San Diego is americanized in comparison to other mexicans, even if his skin color is the same. If he grew up and went to school with nothing but white people, I would say he is "whiter" than his peers back in Mexico. Mastermind would probably have a problem with me saying that since I'm not mexican and couldn't possibly make that judgment.
I don't really think many NBA players grew up in what would be characterized as the "ghetto". And whether or not he came from the ghetto really had nothing to do with the original comment, which was that black people are required to like Kobe or they'd be considered c00ns. Ghettos don't include any certain race and really don't need to be included in a racial discussion. Ghettos can be white, mexican, black, or a combination of the above.
