I would be fine with a firing squad for every single neoconfederate, if it meant every single neoconfederate. Best for the bastards to be quickly removed from society enmasse, so that decent people can get on with rebuilding society without them.

As an ordinary dude, the only real difference I see with hanging and bullets is how much time and suffering leads to the final result. I have better things to do, such as working a job that a neoconfederate can no longer fill.
