The 2a absolutely has it's place, I sure enjoy it. How do we keep ourselves and our already severely stressed friends and neighbors cool and only ready for self defense? All I got that's concrete is what Trump said on j6, go home in peace.
Tell them that normal people aren't represented by the fake news? Rich assholes would love if we kill each other off? An armed society is a polite one? Nothing more rude than blasting someone who doesn't have it coming.
We gotta be ready for max propaganda soon, they're on their last gasp when they raid a (real) President.
You can only do so much on the grand scale but a lot on the small scale. Lead by example. Keep yourself and your immediate family calm by explaining basically what you mentioned. We resist peacefully and use violence in self-defense only. You can do it with your neighbors, too. Why not have a neighborhood meeting discussing exactly this topic? On the grander scale, you can make the case online and inspire others to do it in their communities, as well.
