Excellent article, thanks for posting. I wouldn’t take any commitment on the part of the Left toward the issue of slavery very seriously - “the issue is never the issue, the issue is the Revolution.” Or, if it stirs people up, go with it. That the state of scholarship on the topic is so poor is glaring evidence of this. And the notion that the U.S. is uniquely guilty of anything is based largely on the fact that the U.S. is uniquely susceptible to having its collective pockets picked while being distracted by a passionate guilt trip.
The loveless, ungrateful, proud, self-serving, envy-bitten father of Leftism is Cain. Seeing himself as perfect, thus in no need of repentance, he preferred the devil to his true Father who he resented for what he took to be God’s favor toward the good-goody Abel. Desiring revenge he took the advice of the serpent and bludgeoned his brother to death. Cain’s modern progeny out did Cain when they (Marxist Communists) slaughtered in excess of 150,000,000 image bearers of God and his Progressive brethren murdered over 60,000,000 unborn and just born image bearers.
