“But you feces continually use their designation in a derogatory way.”
False. It’s used in a euphemistic way. A code word if you will. “Feces” therefore would not work as a code word for “Whites”. Thus, whenever you hear about Whites doing something generally out of character for Whites (e.g. rioting over court cases in which a White man who was obviously guilty was in fact convicted, or a White man fathering 10 to 20 children by 7 to 13 different mothers, or a White family living on welfare for 4 generations, or Whites failing school because getting good grades would be a betrayal of their race, etc). the proper euphemistic term would be “Black” - the exact opposite of White. Wouldn’t that just create more problems?
Back when I waited tables, we referred to them as “Canadians.”
“Dang it, they just seated me with a bunch of Canadians, so much for getting a tip.”
