The Left has gone from telling white people they are murderous and evil, to complaining we're too polite.
I saw a tweet recently where far-left activist Muna Mire claimed that white people are too polite. She said civility is white Anglo culture and shouldn't be forced upon Africans and Jews.
People like Muna Mire have replaced etiquette with political correctness. Our system of etiquette and manners has served the Western world well, and there's no good reason to switch to the left's angry, vicious, and nasty alternative.
