He didnt urge its passage. Stop f**ing lying.
I keep pointing this out to you people because you need to have this unpleasant fact shoved right back up your @$$!
What your ancestors did was evil. You didn't murder people in the South because you cared about slaves. You murdered them because a f***ing dictator had cleverly manipulated your ancestors into stopping those people from getting away from Washington DC's control of their economy.
Pretending it was about slavery was just propaganda, and Lincoln would lock up anyone who challenged his claims. Since he involved so many northern people in the evil done to the South, they had no choice but to parrot the claims that they were "dying to make men free." This is laughable because these were men whom they would rather see dead if they had their choice about it, because virtually everyone in the north hated the black men at this point in history.
Lies about what happened have been put forth ever since, and inconvenient facts that clarify what happened, such as Lincoln's support for the Corwin Amendment, or the Warships "supply mission", are omitted because they reveal what was really behind the invasion of the South. *MONEY*.
