Which “states rights” specifically? The only one the rebel states ever mentioned was the “right” to own other human beings.

As has been pointed out to you endlessly, Every state in the Union already had that right, and Lincoln was going to make sure that this "right" would be even more protected than it already was.

Which made the slavers actions even more stupid and treasonous.

As has been pointed out to DiogenesLamp endlessly, nonsense piled on top of nonsense does not make any of it true.
So Lincoln, for whatever his "political incorrectness" in today's historical context was in fact the first openly anti-slavery President ever elected.
That's why Deep South Fire Eaters declared secession!
