> Instead of preparing yourself for some Mad Max bullshit scenario where you imagine you will play hero, having never done it before in your life, just work on continuing to improve supply chain, emergency response and so forth -- in other words, keep building a more reliable and more civilized civilization. That is your best bet right there.

I agree with this in part. Firearms proficiency is a skill that you need to acquire and maintain if you want to be able to use a gun to defend yourself and your family without accidentally shooting them. This is a skill you can acquire with classes, but merely having the pistol/shotgun won't make you safer automatically.
