Listen, son. I am not an advocate of slavery, I don't excuse it, but I have the advantage of hindsight that our forefathers did not. You sound like a liberal on a conservative board.
Washington, Jefferson and other forefathers condemned slavery. From 1820 to 1861, southern political leaders fought not only to expand it, but to shut down any discussion of the matter in congress through the gag rule. Why did the south want more slavery? And given that it was increasingly profitable, what do you think would have eventually caused them to give it up peacably?
You sound like a liberal on a conservative board.
Just a guy who knows a bit about history, including the unsavory bits. You, on the other hand and given your screenname, sound like an unreconstructed Lost Causer.
