*cough* bullshit *cough*
I'm going to address a pretty big misconception that you continue to ignorantly spout. The confederate monuments are not tombs honoring literal fucking traitors, people who killed American soldiers.
Those monuments were built during the era of Jim Crow laws, between 1900 and 1920, more than 60 years after the civil war. some of those were unveiled by members of the KKK.
There was a second spike of monument construction during the '50s and '60s during the civil rights movement. So they aren't tombs honoring American killing traitors. They are permanent hostile messages to African-Americans
Most importantly, Robert E. Lee opposed confederate war monuments. In his writing he cited several reasons for opposing such monuments. He wrote about a 1866 proposal
"as regards the erection of such a monument as is contemplated, my conviction is, that however grateful it would be to the feelings of the South, the attempt in the present condition of the Country, would have the effect of retarding, instead of accelerating its accomplishment.
further he believed countries that erased visible signs of civil war recovered from conflicts faster, and that by keeping these symbols alive, it would keep the divisions alive.
Lastly I would like to point out that he also opposed secession, but was honor-bound to fight for the Confederacy.
so imma call bullshit to your argument. Don't bring up Lincoln. He wasn't a traitor. Don't bring up The Union. They didn't kill 620,000 Americans.
the constitution does not allow for succession. it does not even mention it. and in case you aren't satisfied, the Supreme Court has consistently interpreted the Constitution to be an "indestructible" union. That isn't the modern day court. During the December 1868 term, the case was argue before the United States Supreme Court in the case of Texas vs. White. The verdict, read by Chief Justice Salmon P. Chase on April 15, 1869;
"ruled in favor of Texas on the ground that the Confederate state government in Texas had no legal existence on the basis that the secession of Texas from the United States was illegal. The critical finding underpinning the ruling that Texas could not secede from the United States was that, following its admission to the United States in 1845, Texas had become part of "an indestructible Union, composed of indestructible states". In practical terms, this meant that Texas has never seceded from the United States."
So no. Succession was never legal in the first place. They were Traitors. Those are the facts. End of story.
