because the Mayor eats with his fingers or something.
Yes, that was pretty gauche. It's weird eating a rice dish with fingers.
You may counter that we eat foods like chicken wings and sandwiches with fingers too, but I would say that a) it is qualitatively different than rice, and b) people don't usually eat those foods during interviews.
If a southern Republican moved to NYC and ran for office (a real-life Arthur Branch perhaps?) and he stuffed his face with barbecue ribs or lemon pepper wet wings, he would also be seen as
nekulturny. Why should Rafiq Zohran be given a pass just because he is Muslim?
