I came across and excellent reference article which gives an old school discussion of West African slavery. Whites did not play the major role in this, contrary to the present white guilt black arm band narrative, and slavery networks existed in West Africa long before whites got involved. “The woke will never mention the 800 years of an East African slave trade conducted by Arab merchants up and down the Indian Ocean coast. The woke won’t utter a word regarding present day slavery across the Sahel countries of Mauritania, Mali, Niger, Chad, and Sudan. One hears only silence from the woke when one mentions the “Systemic Ethnicism” that permeates every Bantu nation where wealth and power are concentrated into the hands of a dominant ethnic group.”
