If you let Democrats turn most of the red states and red Congressional seats blue because you said fuck it and you aren't going to vote again, then not getting Congress back in 2022 or the presidency back in 2024 will be the least of our problems.
A supermajority in Congress and the state legislators can amend the Constitution, and that's exactly what power you will give Democrats if you stop voting because they sure as hell won't stop voting. In fact, some of them are probably here posing as Trump supporters and saying they won't vote again because that's what they want you to do while they continue to vote blue themselves.
Some of the bullshit new Amendments you can expect Democrats to put in place if they get the supermajority they need would be a repeal of the Second Amendment, getting rid of the Electoral College, so the president is elected by popular vote, and changing the First Amendment so you can go to jail for what they consider hate speech. Imagine going to jail for misgendering someone, making "back to the kitchen" jokes, or criticizing Islam.
They may even go for broke and remove the natural-born requirement for the presidency, so someone like Ilhan Omar can become president.
TLDR, don't stop voting.
The Constitution has been toilet paper for decades when the term "shall not be infringed" doesn't mean shit to them and hasn't for a while.
You're fucking delusional, naive, and historically ignorant if you think "VoTiNg AnD cALLinG LEgiSLaToRs" is what's going to reverse the course. They don't give a shit about you. They're not accountable to you. They don't answer to you. As far as they're concerned, they don't owe you anything. The masses will have to have the boot crush their necks more for anything to change.
If allowing the left to wreak havoc and destroy this society is what's going to get people to start waking up, then I'm ok with it. The past few months have shown me that the right is mostly full of spineless idiots and grifters not worth fighting for. They'll learn the hard way what live-and-let-live "tolerance" results in.
So your solution to the fact that Democrats are de facto shredding the Constitution with their slim majority is to give them the power to de jure shred it in hopes that it lights a fire in patriots that didn't do enough in your opinion to stop Biden from being installed as president?
If you believe most of the people on the right are cowards because they didn't stop Biden from getting in the White House, what makes you think they will suddenly find their courage and resist with force when the left ratifies the 28th Amendment, which would probably be a full repeal of the Second? What makes you think China won't swoop in and fuck all of us up while we are distracted during our war with our political opponents?
