Kendi misses an obvious point. The only question in America today that is analogous to the slavery question of the 19th century is abortion.
Is slavery morally right or wrong? By the mid 19th century many were saying it was wrong, in fact so wrong that some believed violent acts against it were justified. See John Brown
On the other hand slavery was perfectly legal in slave states, had long been practiced and was Constitutionally protected.
Is abortion morally right or wrong? In the late 20th and early 21st centuries many are saying it is wrong, in fact so wrong that some believe that violent acts against it are justified.
On the other hand abortion is now perfectly legal in all states and is currently Constitutionally protected.
So, how does Kendi feel about abortion which has taken the lives of so many black babies?
His silence on the topic is damning.
