But, but, but, Corwin Amendment!
Seriously, yours was a nice write-up - very thoughtful. Unfortunately DegenerateLamp is hidebound and impervious to reason, persuasion, or common sense. It doesn't help that he is one of those who learned everything he knows by talking.
The simple truth is the slavers were making money hand over fist. Their primary concern was maximizing profits and crushing anything - or anyone who interfered. They saw the writing on the wall - and ignored its very plain import. They gambled everything, and lost.
Of course the Dim One is impervious to reason. But I soldier on in hopes that those monitoring this site see that not all Freepers are slavery deniers.
