Even if you don't like guns and don't want to own one, you should know how they work and how they are used properly.

Kids used to be taught gun safety in public school. Public schools used to have indoor ranges (I've seen one with my own eyes).

When someone learns gun safety, they are less likely to accidentally shoot themselves or someone else if they come across one.

It's not that helpful. What stops this technocratic authoritarianism is shutting down the electrical grid. If that happens the surveillance state dies instantly and all of the top echelon becomes vulnerable again. They live in a house of straw.

How could that help? The fascists have bigger guns and more brownshirts.

If you survive the initial encounter, you're on the run and an enemy of the state?

Find like minded people you can trust and know who will have whose back if something really goes wrong. Also have a passport and some cash, crypto and/or jewelry to get you out if this goes too far.
