Unfortunately, history being what it is, it seems one can't defend the South without slamming the Republican party, which is also wrongly accused of anti-Semitism.
PS: There was plenty of anti-Semitism in the North, but Lincoln was not an anti-Semite.
He accuses Sherman of antisemitism, which is the first I've ever heard of. He does not give any specific facts to show it, however. I can understand someone of his background calling Sherman a lot of names.
