So Lincoln was so pro slavery that he signed the Emancipation Proclamation, and supported the 13th Amendment.
He was opposed to the kind of slavery that southern slave holders wanted to establish: The kind that would have forced northern states to permit and support southern slavery.
The US government made war when necessary to put down an illegal rebellion, and only after being attacked. The southern traitors rebelled to support and extend the institution of human slavery, and made war when it was not necessary to support their illegal rebellion.
May all southern traitors rot in hell.
You ignore history because it doesn’t favor your fantasy world. Lincoln was without question willing to allow slavery to continue in order to win. But he was ambivalent, so he chose another gambit, which was pretending that he had the power to free them by proxy in order to create unrest. It was a war tactic, not an effort to help people that only months earlier he was willing to throw under the bus. What I am saying is historical truth, but somehow Lincoln has escaped into a wormhole and had been allowed a free pass on this issue. Lincoln was the traitor. He stood by as tens of thousands of Americans of every stripe slaughtered each other, and only cared to free the slaves when he thought that they may also somehow be employed to help with the carnage. Sorry Bud, lay it on the table and look at it for the first time in your life. Lincoln’s folly was an epic failure.
