“Never said that the Civil War was all about slavery.”
You are right; you didn’t say that.
The way I phrased my response implied you did, or might have.
I should have made it clear that others have said “it was all about slavery.”
It seems like you have said “if it hadn’t have been for slavery there would have been no war.”
It is a complicated thing. Of the 13 original states, 13 of them were slave states. But of that number, only 13 of them voted to enshrine slavery into the United States Constitution.
I am not totally convinced that the Union slave state of Maryland sent troops to fight in the slave state of Virginia to free the slaves.
Or that the Union slave state of Delaware sent troops to fight in the slave state of North Carolina to free the slaves.
Or that the Union slave state of Kentucky sent troops to fight in the slave state of Tennessee to free the slaves. And so forth and so on.
Jefferson Davis once took an oath to defend and protect the pro-slavery CSA Constitution.
Abraham Lincoln took an oath - twice - to defend and protect the pro-slavery United States Constitution.
No doubt, many northerners did not consider their actions in order to end the slavery practices.
Again, the dicussion in not about what it was. Remove the word slavery from your argument and the discussion takes on another face. Virgina for one was the most industrialized of the slave states and minus the slavery issue would have lined up with the Northern states in any otherwise gendered secession. Without Virginia a secession would have been greatly different. Might have even been mutually agreed upon.
Slavery, if not the wedge, was certainly the glue that held the south together.
