I couldn't be more wrong about the fact that Lincoln tolerated Union slavery for the entire duration of the war? Oh, you put the word "Views" in there, as if we are supposed to draw a distinction between what Lincoln said and what he did in fact do.
Yes, Lincoln's rhetoric was all about being against slavery, but his actions were to tolerate it in areas under his control, and he did so for the entire war. He also supported the Corwin amendment which would have made it far harder to ever get rid of slavery. He also attempted to reassure the Southerners that he would do nothing to eliminate slavery if they would just stop fighting and rejoin the Union.
I'm sure Lincoln's preference was to get rid of it, but his pragmatism made it clear that he was willing to live with it indefinitely.
No, not "pragmatism", it was Lincoln's commitment to the US Constitution, which recognized slavery and could only be overturned by constitutional amendment -- the 13th Amendment.
But Lincoln also knew that Civil War created "contraband of war" escapees he could, as commander in chief, order emancipated pending ratification of the 13th Amendment.
We should note also that Lincoln's Civil War strategy very likely came originally from our Founders, through one of their youngest, former President John Quincy Adams.
For the last two years of his life Adams mentored 38 year-old Congressman Lincoln, including Adams' ideas on emancipation if the South seceded.
