There's a woman in my city who's made wearing shoes indoors her whole identity (she even changed her Twitter username about it). Such a weird concept to me...
You should not rinse chicken (or meat) in the sink, it's a) useless if you cook them properly (as in, not eat them raw), because that will kill the bacteria and b) potentially harmful because you'll splash around the bacteria on your sink/utensils etc where they will remain dangerous since they won't be cooked.
idk what the original commenter meant, maybe he missed a negation and wanted to say that white people rinse their meats when they dont have to? because that makes more sense to me
