Amazingly full of factual errors. Confederates did in fact attack Washington. Slave masters were fighting a war of independence? Independence for who?
For themselves, same as the 13 Slave holding colonies led by the Slave holding General Washington.
Stop trying to pull the old bait and switch. Slaves didn't have rights recognized by the Union at that time. Stop trying to apply rules from 4 years later to 1861. That is just deceitful.
I know why you do it. You do it because all your justification for invading falls apart if you don't do it.
You don't have a moral or legal leg to stand on unless you apply rules from 4 years later to 1861.
