It doesn’t look to me like the Repubs are totally trying to end democracy, at least not in the sense of establishing a Stalinist or Maoist or Hitleresque regime. (That can come later.) They are “merely” trying to establish total Republican control of all the levers of government in perpetuity; democratic elections be damned. That’s bad enough. The current fear is that the are this close → || ← to accomplishing that, and the upcoming 2022 mid-terms will determine if they succeed.
We’ve had past spells of Republican control. The nation didn’t implode, at least not totally. Those were bad times for human rights, civil rights, and the economy (unless you were very rich). But the pendulum swings, and periods of more enlightened and progressive Democratic control happened too. What happens when the Repubs take total irreversible control is that there won’t be any more swinging of the pendulum (unless it just keeps swinging further right).
What happened during past periods of Repub control was that American life went on, more or less, preferably if you were sufficiently White, Male, Christian, and Straight. Not so much for all the others.
But once Repubs get total irreversible control, they will be unobstructed in their further atavistic goals. Civil rights will be withdrawn. Obamacare, Medicare, SSI, SSDI, even Social Security will be on the chopping block. Those of us already on Social Security will probably be grandfathered, but this and other safety net benefits will be phased out by and by. The First Amendment will live, but under duress.
As for myself: As several others have said, I’m a bit too old (69 going on 70) to put up much of a fight. I think I will largely, but not entirely, keep my head down and keep my mouf shut. But I will resist where the opportunity arises, within the limits of my energy and enthusiasm. Perhaps I will join marches, etc. Perhaps I will volunteer my time for some kind of resistance movement. I will certainly grumble. I doubt that I would take up arms. Maybe I will surprise myself and become more active that I am envisioning here.
But I might also console myself, saying that we Americans collectively, by letting this happen, are no longer fit to live in a democracy anyway. Churchill reputedly said “In a democracy, the people get the government they deserve.” Whoever said that, could it be right?
