What is racist about making that statement? People need to get a better understanding of racism. If the PGA tour wouldn't allow Tiger Woods to play in their Association because of his skin color, THAT would be racist. Sergio joking about serving tiger fried chicken is just a stupid joke, based on a cultural stereotype. As a society, we allow for cultural or racial stereotypes, as long as they're positive (Asians are good at math, black guys have bigger schlongs), or as long as they're targeted toward the dominant cultural group (white men can't jump). The last remark, at the very least, is a racial remark, because it's based from a biological perspective. A black guy eating fried chicken isn't racial, it's a cultural stereotype, and not even a very good one at that.
Sergio comes across as a bozo, but if we strive for accuracy, let's call a spade a spade...oops, I hope I didn't offend anybody with my "racist" remark.
