There's a lot of important & worthwhile stuff here, especially the anti-black riots that destroyed much of the progress freemen & women made in the post-war era. Most people also believe the KKK was responsible for most of the anti-black violence & "redemption" of the south to white supremacy, when they were actually fairly minor players compared to the Red Shirts & White League, which were far more numerous & active in suppressing black vote & representation.

Nevertheless, I have to take issue with several points here. That Martha Washington freed slaves for fear of her safety begs the question of whether or not the slaves would have been aware of George Washington's will. Is there any evidence they were?

Then Lincoln. Yes, the Emancipation Proclamation didn't free that many slaves, but in addition to keeping Europe at bay & the Border States aligned with the Union, it permitted free negroes to join the Union Army & fight for their freedom.

Lincoln is taken to task for his seeming reluctance to free the slaves, but what was important was his commitment to keeping the Union intact. Without it nothing, nothing positive could happen for slaves. Perhaps a part of your proposed "white history month" could include reminding people that many prominent abolitionists were also pro-secession. They weren't willing to go to war to maintain the Union, while Lincoln was.

What was more important?

Further, Lincoln worked fervently behind the scenes to pass the 13th amendment, which did free all the slaves. Though he was killed before its ratification, that it would be ratified was fait accompli before his murder.

His comments about black people quoted from the Lincoln-Douglas debates took place in 1858, before he met with Frederick Douglass or had the opportunity to witness the valor & heroism of negro troops when given the chance to fight. Only a very unintelligent person doesn't change his opinion in light of evidence to the contrary, & Lincoln was intelligent.

The irony here is that much of the "real Lincoln" material presented by anti-racists mirrors almost exactly criticisms made by Neo-Confederates or Lost Cause advocates, desperate to prove the war had nothing to do with slavery.
