I consider mostly the internet going out. Gas pumps not working for a month or so and what that means to most people not prepared. I’ve camped several times in places with no internet. Now have antennas because experience was brutal.
But in seriousness I think Americans would be kind to each other if something less than pure chaos happened. I don’t think most people are itching for reason to pop off. It would have happened already if that were the case. Being prepared is common sense. Be prepared.
