@BillRM,
Most White people don't object to berating their ancestors for having supported slave trade . That's why The Economist, which has lots of white writers and editors, doesn't shy away from telling its readers that "of the seven most important Founding Fathers, only John Adams and Alexander Hamilton did not at some point own slaves. Nine early American presidents were slaveholders," in an article published this month.
At the same time, some black writers working at The Washington Post and the New York Times have spouted racial slurs designed to vilipend white people. The Post's Karen Attiah, who's black, tweeted,"white women are lucky that we are just calling them ‘Karen’s. The Time's Bari Weiss, a white columnist who wrote a book on anti-Semitism, had to resign after being buffaloed by other liberal writers calling her a dissenter; they call her this because Bari Weiss takes issue with cancel culture. Ibram X. Kendi, co-author of " Stamped: Racism, Antiracism, and You", reportedly remarked that there is no room for racial equality insofar as white people rule America-by which he meant seizing leadership would be the only way to create Black America.
Some black supporters of BLM seem to be fans of Nation of Islam as well; they hate both white people and the Jews. Rashida Tlaib and Ilhan Omar , who are black Muslim Democrats, have despised Israel publicly while voicing support for terrorist groups. In other words, they have form.
Biden should give such agitators a wide berth if he wants to trounce Trump. He should realize that his voting base doesn't include far-left sorts and haters like Rashida Tlaib and Ilhan Omar.
