Actually, Tiger invented a word to describe his ethnicity, “Cabalasian,” as sort of a joke meaning caucasian, black, american indian, and asian.
He really looks Thai more than anything.
Do you remember that Olympic swimmer from a couple of Olympics back who was one-quarter black? Every TV journalist would start the interview with something like “Do you hope you’ll be a role model in the African-American community?” He was clearly getting sick of it, would glare at the interviewer and say something like “I hope I’m looked on favorably by all American communities.”
The liberal journalists would stammer for a few seconds and then go right back to the “African American” this, that, and the other thing while the athlete looked like he wanted to hit somebody.
You'll notice that Derek Jeter has spent at least the past 11 years ignoring these sorts of questions. Which probably had something to do with why Gary Sheffield called Jeter a "half a n-gger" after he accused Joe Torre of being a racist earlier this season.
