Mississippi’s prisons are worse by no small magnitude compared to other usa states

Still apparently legal under American federal law, last I checked Mississippi is part of USA. And federal law in USA doesn’t protect human rights very well, which is very contrary to EU.
So even if AfD becomes part of a coalition government in Germany, they have to observe human rights under EU regulation.
As I mentioned many aren’t even aware how bad it is in USA, and you seem to be one of them if you are American.
