You didn't read the whole post, did you? You made a claim I asked you to support. You also, I note, completely ignored Lincoln's anti-slavery positions and actions.
In sort, you are evading by focusing on a throw-away comment with faux outrage.
Give it a rest. Anyone who wishes can read the exchange. it's clear what is happening.
However, for the benefit of those who don't want to go look at it. I wrote a post where I said Lincoln wasn't an abolitionist and didn't run as one. I also noted that, technically, Lincoln didn't abolish slavery, because he died before it could happen.
Upchurch "corrected" me, saying he ran as an abolitionist in 1864, and that he would have abolished slavery, but he died before it happened.
But, rather than all this posturing, let's try an get back to the original point. (Upchurch sometimes calls this "moving the goalposts") Although I didn't identify it as such, it was really a reaction to Travis' "over the top" post. My point was that Southerners weren't really as bad as they were being portrayed. Yes, they supported slavery, but people all over the country supported slavery. Support was dying for it, but it hadn't died. Opposition to slavery had not yet achieved majority status, even in the North. (Upchurch did have one legitimate point to make. Support for abolition was not the same as opposition to slavery. There were many northerners, maybe even a majority, who thought slavery was wrong, but weren't willing to support abolition.)
It made me think about moral relativism. Even though the South was engaged in what we would consider a great evil, nevertheless there were good people among them, just as there were good people among other evil nations, like Nazis and Aztecs.
And the point of all that? Once again, not made explicit until now, was that guy underneath that tombstone might not have been a bad fellow. It's ok to decorate his grave with the flag he fought for.
I might add that a flag on a tombstone serves as a reminder of how that guy got there. That's not exactly an endorsement of his cause.
