That whole argument is ridiculous nonsense since, among other reasons, the very words "racist" and "white supremacists" were not used in those days.
Yes, similar ideas were there, but they were expressed differently, and generally were taken for granted and so not debated.
What was discussed at great length was abolition and issues related to it, such as fugitives or "sojourning" with slaves into free states.
Lincoln favored abolition and opposed slaveholders' lengthy "sojourns" with slaves into free states.
That's what mattered in the 1850s, all this other language was not used and was irrelevant to debates of the time.
By 1865, Lincoln had come to support not only abolition but also full citizenship for freed slaves.
That's what got Lincoln assassinated, according to John Wilkes Booth.
So, can we stop babbling nonsense about "Lincoln the racist"?
That is an irrelevant argument. Whether they were used in those days or not, in the modern understanding of those words, Lincoln and everyone else were "Racists" and "White Supremacists."
What was discussed at great length was abolition and issues related to it, such as fugitives or "sojourning" with slaves into free states.
What was discussed were various plans for keeping the whites and the blacks separate. Lincoln had numerous discussions on methods to get the blacks out of the country. He even implemented some of the plans to do it, which turned out to be a disaster for all involved. I think it was attempted on the Mosquito Coast of South America. The vast majority died.
According to Union General Benjamin Butler, the very day Lincoln was assassinated, he was discussing another plan to get blacks out of the country.
By 1865, Lincoln had come to support not only abolition but also full citizenship for freed slaves.
Because they were guaranteed to vote for him and his party. This was just a cynical political usage of them. They were useful to him, but in reality, he wanted them out of the country.
So, can we stop babbling nonsense about "Lincoln the racist"?
Sure. Just tell us this isn't the hill you wish to die on, because the evidence that Lincoln was a "Racist" is overwhelming. If you want us to bring quotes, we can bring quotes.
You know i'm right about this, you just hate to admit it.
I understand the desire to not admit any flaws in people you admire, but even Trump has his drawbacks.
Still best president ever, but only Jesus was perfect.
