Even if its not- it should be legal.
Just saw this argument:
“The South seceded. That made the war necessary. The South could have just peacefully remained in the Union.”
AKA: My wife wanted a divorce- that made beating her necessary. My wife could have just peacefully remained married to me.
Abraham Lincoln saved the union the same way that an abusive husband saves his marriage- by saying you aint going nowhere, bitch.
The federal government has too much power. The idea that the federal government tells the state's what to do is flawed.
