(I’ve since Re read the original discussion, thank you for the link.)
Oh, I think some of this is about the language used in current academia. But genealogy is different, it’s artifact based.
I’ll repeat my original test: on the three names - American Enslavers, American Slaveholders, American slave owners - what does google show?
American Enslavers
Is enslaver a word?
To make into or as if into a slave. en·slave′ment n. en·slav′er n

Enslaver versus Master, Owner, or Slaveholder
An enslaver exerted power over those they kept in bondage. They referred to themself as a master or owner - hierarchical language which reinforced a sense of natural authority. Today, the terms “master” or “owner” can continue to suggest a naturalness to the system while also distancing us from the fact that enslavers actively enslaved other human beings who were entitled to the same natural rights as themselves.
The terms slave master and slave owner refer to those individuals who enslaved others when slavery was part of American culture. These terms can imply that enslaved people were less capable or worthy than those who enslaved them. Using the word master or owner can limit understanding of enslaved people to property. These terms also support a social construct that there are people who should naturally hold power (i.e. slave owners, slave masters) and those who should naturally not (enslaved individuals).
