Indentured servants? How about outright slavery in maryland and delaware?? LOL don't let THOSE facts trip you up. Why did the great emancipator refuse to emancipate slaves under his control?
He didn't. The 13th Amendment was passed and sent for ratification while he was president.
The only thing "tripping you up" is truth. You're clearly a Lincoln-hater and will use any deception to conceal the fact that slavery was the central issue in the Confederacy, and the sole reason they saw Lincoln as a threat.
