Remind him all the Confederacy was Democrat.
But then, who the hell cares about that scrap of paper??
You might also remind him that is the Confederate Battle Flag is to be discarded ober the issue of slavery, then he had better start another crusafe -- to quickly get rid of the Stars and STripes. Slavery flourished far longer under that banner than it did under the St. Andrews Cross (or under the real "National Confederate Flag". And he also, might be reminded that what Southerners choose to do to honor their ancestors, is none of his damned business. And to nail the Nazi label on something he is too ignot=rant to understand, show him to be a total nincompoop.
Aside from that --- UH ---- there is still doesn't seem to be anything that can be said in his favor.
Yep, and Northern Democrats in 1864 ran on a platform of surrender, and allowing slavery to continue.
After the war of southern treason (civil war), the Democrats formed the KKK and lynched blacks as well as anyone else that tried to vote Republican.
