Voting for Democrats is the "leaving the house, getting some exercise, and drinking more water is good for your mental health" of societal change. Everyone keeps telling you to do it, worst of all your mom keeps telling you to do it, and it's not a magical cure-all, but it actually works and rotting in your room shitposting does not help in either scenario.
Also like mental health, voting doesn't solve the whole problem! But if you aren't doing this bare minimum thing, the other tools you have aren't going to work as well as they should either. If you get medicine and continue rotting in your room shitposting, you will probably still be miserable. If you get a union at work but don't vote for politicians who support unions, the union won't be able to advocate for its members as effectively and work will still be miserable.
Voting is maintenance. It's like doing the dishes or cleaning the leaves out of the gutters. You're never going to get to a point where you are Done and Never Have To Do It Again (alas,) because time will continue to pass and you will continue to eat meals and the trees will continue to drop leaves into your gutters and right wingers will continue to submit bad bills to every session of congress.
You'll never be done with maintenance. But if you don't do that maintenance, your situation can and definitely will get Worse
Finally a take on the 'vote or else' shit I can vibe with. It's currently like showering with dysphoria- miserable and annoying with no real positive outcome past the current state not rapidly getting worse, but that's better than the alternative of things rapidly getting worse
