Abraham Lincoln's views on race, it is a well-documented and self-evident fact, evolved over the course of the war

So not only did his views on white supremacy never actually change, but the most he even conceded was that "some black people should maybe be allowed to vote"...which is still far from the "black equality" you suggested.

Secondly, yes, of course it would be an oversimplification to believe that the party switch was some kind of direct 1-to-1 swap, instead of a decades-long evolution/devolution of mainstream party policies and values and voter bases, but it was still a generalized switch nonetheless. Considering I already know from our previous engagements that you are a party switch denier, and also a far-right religious middle-schooler, it's pretty clear that you have not "studied history for any significant amount of time" regardless. Do you need me to disprove your young-earth creationism again too, because that's also pretty blatantly ahistorical...
