I will accept your inability to give a direct A or B answer as you conceding that 2026 is the correct answer. For the record, the South was becoming less racist long before the stuff you mentioned happened. You realize there were anti-segregation protests all over the South, right? In other words, the Democrat Party lost because the South had already become less racist as it became more Republican.
Now look at the inverse. Boston was the epicenter of the abolitionists leading up to the Civil War. Bostonians were far more anti-slavery than Lincoln ever was led by Charles Sumner and the "Radical Republicans." When do you suppose racism peaked in cities like Boston?
Obviously when the Democrats showed up and started imposing their racial hatred on everyone.
