Try to be patient with yourself. Slavery was a losing issue long before you were born. Try not to personalize it. None of it is your fault. ;-)
SO, you are back to the smear. Anyone who disagrees with your adoration of Lincoln and the leviathan federal government must be in favor of slavery. You are conceding that you have no real argument. This is the sort of thing liberals do. Given your resort to the jurisprudence of the “Living Constitution” and disregard for the actual provisions of the Constitution, I’m not surprised.
