“Dictator” might be taking it too far, but he was certainly no angel of democracy during the war of Northern Aggression.
I've always preferred the term tyrant.
Now, if the originator of this thread wanted to take the "pro" side of the "resolved" "Lincoln was a Christian," well, then, he'd really have his work cut out for him.
Caveat: I think Lincoln was one of the 2 or 3 bona fide geniuses to ever hold the office.
He was a tyrant, though....and a white supremecist.
