Glad you recognize that fact. To defend the Confederate Constitution was to defend the institution of Slavery. Didn’t say anything about the war, just that Davis sacrificed thousands of Southerners to defend the Confederate Constitution, which made slavery mandatory in the Confederate States of America. Once you are up to speed on that subject, we can talk about it
You are giving us a bait and switch. To defend the US Constitution of 1861 was to defend the institution of slavery, because the US constitution specifically protected the institution of slavery.
Stop trying to put slavery only on the South. Slavery was part of the Union, and it lasted six months longer in the Union than it did in the Confederacy.
The was wasn’t about that. Slavery was done for regardless, industrialization was taking over, it was only a matter of short time. I’m not for slavery obviously, but there was far more at play there.
