The modern Republican Party is nothing like the Republican Party of Lincoln's era. Modern Republicans are actually a lot more like the Democrats of the time period now.
I know. I, too, have grown weary of having to refute the right-wingnuts who somehow believe (to keep from some measure of self-reflection, I suppose) that because Lincoln was a member of the party and because he signed the emancipation proclamation that it makes a desire to see white male Christian privilege keep on keepin' on is somehow okay and not racist.
I don't think this is trolling. I went through four years at Ole Miss where I heard this exact line of thought from more than one white southern gentleman.
