Swahili is a common language. Several Kenyans I know speak their tribal language, English, and Swahili. It is spoken in Kenya, Tanzania, Comoros, Mayotte, Uganda, Rwanda, Burundi, eastern Congo, Bajuni Islands (Somalia), northern Mozambique, Zambia, Malawi, and Madagascar.
“Swahili is a common language.”
I have to ask: did the tribes that spoke Swahili ever participate in slavery or the slave trade during the past 6,000 years?
Did any of those tribes know about other tribes that did participate in slavery, and do nothing to prevent it?
If so, Swahili should not be taught.
