Agreed. I remember reading years ago that part of the Christian abolitionist movement here in America was that if it was wrong for whites to be slaves in North Africa, then it's wrong for blacks to be slaves in America.
IIRC the numbers, 350K to 500K blacks were brought as slaves to America. And 1 to 1.2 million whites (mostly from Europe but a few were Americans captured on ships) were taken to North Africa as slaves.
