Actually, it being Kenya, the Luo slavetraders probably sold their prey north to fellow Muslims, who castrated the men, raped the women, and worked both to death in the fields and mines. There is a reason there is no black diaspora in the Arab world, despite far more slaves having been sold north than ever went across the Atlantic.
But your general point holds.
Thank you. I have been so busy over the years I never studied African history enough. The subject is on my list.
