I reject your premise. I'm sure there were many 'good' slave owners who kept their slave families intact. But I can't believe you are a supporter of slavery. Slavery is a crime against humanity. It is the antithesis of American values.
Your statement >>Where he is dead wrong is his belief that slaves had a family life. << indicates there was no family life for the slaves.
Now you’ve changed your song. >> I’m sure there were many ‘good’ slave owners who kept their slave families intact. <<
Make up your mind which side of the fence you’re on.
