In response to rightwing gun nut excusa-holics that make up cures gun ownership would have prevented like “Hitler” being defeated by gun owners (See my post: Hey rightwing gun nuts, Hitler was not afraid of rounding up armed people - ask all the armed nations Hitler invaded.) the other meme is that if slaves owned guns they would have not been slaves.

Apparently, the rightwing gun nut universe avoided Black history studies in college because they would know that the gun trade and warfare against other tribes (also armed with guns) fueled the slave trade. Pretty much all of the slaves brought to the Americas were victims of gun violence (the losing side in tribal warfare).

Along the west coast of Africa, from the Cameroons in the south to Senegal in the north, Europeans built some sixty forts that served as trading posts. European sailors seeking riches brought rum, cloth, guns, and other goods to these posts and traded them for human beings. This human cargo was transported across the Atlantic Ocean and sold to New World slave owners, who bought slaves to work their crops.

European traders such as Nicolas Owen waited at these forts for slaves; African traders transported slaves from the interior of Africa. Equiano and others found themselves sold and traded more than once, often in slave markets. African merchants, the poor, royalty — anyone — could be abducted in the raids and wars that were undertaken by Africans to secure slaves that they could trade. The slave trade devastated African life. Culture and traditions were torn asunder, as families, especially young men, were abducted. Guns were introduced and slave raids and even wars increased.
