I find it sad that in the year 2019, in what is ostensibly the best country in the world, and is by a very long way the richest country in the world that an apparently significant majority of people still think it possible they will have to actually go to war with their own government, and they need to keep guns for that outcome. Brutal, bloody, horrible war where literally tens millions of people will die in agonizing pain. Why the hell is "the best country in the world" thinking about and holding onto it's gun for this?
