We didn't secede from the British? Let that sink in for a moment. There is a cognitive disconnect at work in anyone who could make such a statement. It is an abject denial of fact, the likes of which require some sort of delusion.
You simply cannot wrap your mind around the fact that what the Colonists did with England, is the exact same thing that the Confederates did with the US, and now you are trying to talk yourself into seeing a distinction that doesn't exist.
They made war on us, and we eventually fought back, and eventually we responded to the state of war with a Declaration of Independence.
Yes, the Colonies were just going along, minding their own business when the British "made war on us." Good God man! Own up to the truth! We broke away, intentionally, and for reason's which we thought were good. *WE* shot at them. (Battles of Lexington and Concord.) *WE* killed 73 British Soldiers in the initial conflict. Stop lying to yourself, and stop trying to push your make believe on me.
By contrast, the slave power pretended to secession first, then complained about the crisis they created, as their justification, using secession as their justification to enslave all the poor white males US citizens by conscription (but exempted the wealthy slave owners from conscription).
Your statement above is so ignorant/stupid, that you ought to be embarrassed for having written it. Seriously, "the slave power pretended to secession"? "Then complained about the crisis they created"?
If this is your level of understanding, then it is a waste of time to even discuss this with you. It's like arguing with a child. You need to finish High School, and get into College where you can study some History while developing a more mature attitude.
Try reading some history. A hot war, with invasion of British troops and foreign mercenaries, a war with deaths, sacking of cities, imprisonment of opponents, and blockade of ports had been going on for over a year before the Declaration of Independence was issued.
The Declaration didn't cause the war. The war caused the Declaration.
It was a real Revolution, not an unconstitutional secession.
We didn’t secede from the British - we rebelled against their rule. You’re not stupid, why do you persist in acting like you are?
