I certainly have bias against chattel slavery.
But discussions about “understatement” are about messaging.
So you are correct - “Slavery did limit opportunities for jobs, education, and travel…”
as am I when I wrote that “chattel slavery impaired people’s liberty”.
We all are against chattel slavery, Silly.
But what it was vs. what we think it was today is loaded with discrepancies.
You would be wise to avoid generalizing about the subject.
