Actually, if you read more than your kids book of entitlement, you would realise that the biggest buyer of slaves was other Africans and that it is still going on over there. The Arabs and other non white people were enthusiastic slavers and only stopped doing so after a lot of effort by the British navy to extinguish the trade. Closing your eyes to the wider truth just makes you out to be another grifter who wants to stir up hatred that had long been forgotten about. Be a better person and try to learn that time has moved on.
