Yes, the confederates were complaining about more than just slavery, but slavery was central to secession. In the examples you gave it’s still all about slavery. I think looking at foundational documents and speeches makes it clear that the cause was as simple as “slavery”.
And also white supremacy. All the states that seceded wrote an article of secession and many, if not all, bring up the importance of maintaining the superiority of the white man. It’s insane how people don’t know this. Even if you took out all the parts about slavery there would be a shitload of racism left.
Have you read the declaration of secession?
