Trust me, I know. I’m a Southerner myself. I know that whenever Southerners talk about “states’ rights,” it’s basically as an excuse for us to keep being backwards. I just don’t understand why anyone who doesn’t want to stay mired in the 19th century should care.
I feel the same for country’s sovereignty. There’s plenty of reasons you could give why Country A shouldn’t invade Country B to overthrow their evil oppressive tyrant, both moral and practical ones, but “they’re a sovereign country” is one of the ones that never resonates with me.
