If they go for our guns, all bets are off. Civil War will be terrible, but going into it unarmed would be even worse. Gun grabbing (or even taxation/registration) is the line they cannot cross.
Short of that, this will be economic. I will boycott leftist businesses. All purchases are political, and I will go without rather than support America’s enemies. I am also “buying ahead” - buying now under Trump to make the Biden economy look worse. As much as possible, I’ll withhold new purchases until we have a real President again.
There will also be shooting. The thugs are already shooting at and assaulting real Americans. I expect that to go both ways to an increasing degree. Their infrastructure may also be a target. I’m okay with watching utilities and transportation in leftist areas become increasingly unreliable, as a choice not just an accident.
Finally, we need our own “Long March Through the Institutions” https://en.wikipedia.org/wiki/The_long_march_through_the_institutions . We need to take back our schools, churches, universities, and media - shun those that support pure evil. We need to teach our kids/grandgchildren explicitly things we never thought needed to be said, so we are not providing the foot soldiers for their next generation in this war.
Yeah, you’re right about the long march. The universities are the bastions of the Left. It’s through them that leftist thought pervades society because students who attend university go into all walks of life: law, the courts, media, business, government, arts, education, Hollywood, etc. It’s the university that started this whole thing back when they embraced the Frankfurt School and Post Modernism. Leftist though became fashionable and everybody was reciting the gibberish. If I get started on this I will never end. But this has been a problem that people knew about for a long time — at least since the 1980s — and hardly nobody was willing to do anything about it... but talk. Now you have BLM being lionized by the public and big business. Incredible.
