I really thought about this last year, took the class and everything. In the end I decided not to get one. My reasoning is this: Having a gun and not a lot of experience in what to do with it is like playing a board game for life-and-death stakes that you have never played before.
Maybe I will regret at some point in the future, but I had trouble coming up with scenarios where I wound up thinking "Thank God I pulled my gun out, now all my problems are resolved."
I mean, after a certain point, yes. Solzhenitsyn talked about it, also I think some of the founding fathers had things to say about it. In our current situation, absolutely the fuck not. For one thing, it'll get you killed obviously, for another thing, it'll give them the pretext they're looking for to start with all kinds of shit to all kinds of people that they can't get away with right now. They are praying for something like this to happen. That's why they play up anything which looks vaguely like it into something it isn't.
Every day that goes by where ICE is the illegal mother fuckers and the people of the country are the innocents, is another day they lose a little more backing of the courts, the military, the city police, all kinds of stuff like that which is their pathway to power. I know it sounds like I'm just backing down from fighting back... all I am trying to say is that starting gunfights with the secret police is about like starting a fistfight with your abusive spouse: You're not wrong. But also, you're not going to win through that method.
Here is some extensive information about what does work after quite a lot of research: https://www.files.ethz.ch/isn/126900/8008_FDTD.pdf
