You are correct that is what that means, but my mention of that was about slavery before the US colonies existed. “Indentured Servitude” was a term that first appeared in the 1700s and was basically “non-imported people becoming laborers until their debt is paid,” which then naturally altered the term slaves to be “imported captives that become permanent laborers.” Before that, it was all just called slavery and had the first definition. Obviously that didn’t always go like that, as you know.

In the US colonies and states, I think the safe assumption is that probably almost all of them were racist, or were at least some level of bad. I don’t know if any would have cared enough to specifically not buy non-black slaves, if that is what you were asking. As I said, I never really cared enough about slavery to look for that kind of thing. My curiosity in it never really went beyond historical context.
