I don’t disagree with that. But slavery in the Confederacy was not new. But if slavery was not to be interfered with where it was lawful, how was the war about slavery?
Reread my post #143 and tell me, in what way is it not clear?
That Confederates seceded & fought to protect slavery is indisputable as is: that Unionists fought to preserve the Union first and also to free slaves.
And you've known this since you were a child, so why pretend to make an issue of it here?
