Yes, that is why the truth about slavery must be talked about more often. That is the only way for the truth to finally become understood, when it comes to slavery.
Every race has engaged in slavery in the buying & selling of humans of every race.
The first recoded slave owner in the U.S. was a Haitian who had decided that the indentured servant he had employed, also from Haiti, didn't live up to his indenture agreement, so he decided he would make him his slave, which was upheld in a court of law, not that I agree with that decision.
