Yes.. all slave owners.. black or white.. Jewish or Christian or Hindu or Muslim (who owned slaves till late last century) ought to burn in Hell....
Only God owns us... Jesus loves us... and we belong to Him.. NO ONE ELSE
Slavery was a WORLDWIDE phenomenon. Blacks, Whites, Browns, Yellows, Greens all owned slaves....
.. and I have sympathy for NONE of them...
To our Jewish, Sikh and Hindu brothers.. I said Jesus.. but not trying to impose religion...
God is our master....However you worship Him...
No religious slight was intended....
Why only the last century? What about all the slave owners in the Middle East today?
p.s. You are aware, aren't you, that some blacks in the south petitioned to go back into slavery to be taken care of.
