When people decide to secede and exercise their right of self determination, they don't ask the government for permission or research scotus decisions.
So cry me a river. You asked for constitutional and supreme court references. I gave them to you. Just because someone doesn't want to seek legal avenues does not make their actions legally valid. States cannot exit the Union except through consent, or through revolution. The confederacy chose to give revolution a try. Didn't work.
secession is not unconstitutional. It isn't mentioned anywhere. There is no "legal avenue" to seek, counselor.
The south tried to peacefully withdraw.
Lincoln sent troops to invade the CSA, a sovereign nation, which is an unprovoked act of aggression.
So now you're just blatantly ignoring the evidence you asked for and received, and history as well. Guy, you need to do us Republicans a favor and shut the fuck up. You're the Sandra Fluke of the GOP and you soil us all with your rabble.
secession isn't "unconstitutional". It isn't mentioned in the constitution.
point out the historical error you think I made?
