I do not support slavery, just stating historical facts to help you liberals understand the debate.
What debate? You keep ducking out behind legal technicalities.
It's like this: There are moral and ethical principles, and there are laws. Good people make laws that reflect their good principles. When the laws don't match the principles they are bad laws and need to be changed. The Founding Fathers believed it was OK to revolt, defy legal authority and kill when they thought the laws didn't live up to principles that benefitted them. Then they fumbled the ball.
They staunchly upheld the laws that deprived their black brethren of similar benefits, bloodily punishing and suppressing any attempt to claim those inalienable rights for anyone w/ a drop of African blood. Which racism naturally progressed to genocide of the original inhabitants of the continent. And you're defending them for it.
Conservatives—real conservatives, who try to hold onto proven values—have much to contribute to society and we need them. But the unprincipled BS that shamming pretenders to the name try to pass off—like that sort of pettifogging crap—smears them all.
There isn't anyone elevated to high status, who doesn't stand on feet of clay. Real progress comes when you stop looking up to them and imagining their received wisdom is all you need ever to know. Progressive liberals, as they were, start by examining principles, and using them afresh, as they did, to make changes for the better.
And they don't stop because some bible told them so.
