1 - He literally refers to his wife and her family as not white, so whatever they are he considers them non-white, which is the only relevant part.

2 - It's not racist to assume Mexican people cook Mexican food, nobody is making that claim. He has repeatedly referred to non-whites in mocking and derogatory ways. This includes him literally complaining about his wife's "non-white food" and how he ordered "white people food" to by himself away from his wife and her family because he wants "a white thanksgiving". He asked a gust if his wife was white, and when the answer was "no" he asked in a disgusted tone if she tried to "fill your kids' with that shit" in reference to their own racial heritage.

So no, b, I'm not projecting. I'm not the one doing mocking Asian accents about an American doctor just because he has Asian heritage, I'm not the one eating away from my own family because they aren't white enough, I'm not the one asking people if their spouse is not white and then trying to get the person to prevent their kids learning about their own racial heritage because it's not white.

Are you just a customer that got lost on their way to the toilet and wandered into the kitchen? Because this is a PF Chang's bapa.
