The fact that the Northern Republican controlled congress voted to pass the Corwin Amendment by a 2/3rds margin in both the House and the Senate puts the lie to the argument that the Northern leadership gave two sh*ts about slavery.
Tell the truth. You can't vote for permanent slavery, and then claim you are fighting to end slavery.
But the propaganda still circulates. As Mark Twain said, a lie gets halfway around the world before the truth gets its boots on.
The North didn't fight against slavery. It fought against freedom and independence of people who didn't want to be ruled by Washington DC anymore.
Slavery was thrown in later as a punishment to the South for opposing the DC dictatorship, but it was never intended to be abolished when armies first Marched into Virginia.
Stop whining about a war that was fought against the US, and be concerned with the civil wargoing on aga>nat the US now.
