RvW was overturned under the USian dem government, after decades of promising to codify it, and at a time when all of the relevant judges could have just been replaced.

You people keep acting as if you're being told to roll over and accept defeat. Nobody is saying that. What people are saying is "voting for the lesser evil doesn't work. Its such a dogshit strategy that there isn't any difference between those two parties anymore." And somehow you take that to mean there's nothing to be done. If you are really so hellbent on voting being the only thing you can do, then at least vote for a third party. But really you ought to be doing more than that.

The absolute very best case scenario for a democrat is that they do fuck all. Most of them are far worse than that. They are typically doing the exact same shit as republicans, but no one gives a shit because they're not overt. I am not an accelerationist, so I dont believe its a good idea to concentrate power in the hands of capitalists, so I won't vote for the more competent managers of empire.

In the case of a best-case democrat, you're also making things worse by voting for them, because your vote legitimises their inaction. Every election were democrats have won has been an election that normalised the monstrous. It didnt use to be like this, that you could just shell out cash for cops and child killers. You didnt use to just be able to hand out massive fracking contracts or senselessly pursue brinksmanship without anyone calling you out for the rabid warhawk that you were. Now it doesn't matter. John Kerry ran on being the better guy for the war in Iraq. Obama won his second term on the back of all his warmongering. It wasn't always like this. Decades of the lesser evil has lead us down this path, decades of "well we have to vote for them just this once, its the most important election dont you know" has put us where we are now. It clearly observably does not work.
The very best of the democrats is just a republican a few election cycles behind. And most of them are far below par.
Voting for them gives them legitimacy, its not a harmless action.

And of those that are the very best, they quickly get engulfed and integrated by the machine, turned into the next generation of managers of empire.

Yes, it is clear that you aren't following the logic. Maybe some context will help: The democrats support republican policies when they are in power.

Also, who said that you should "just let the republicans have more power"? I didn't see anyone even suggest that.

Doesn't seem like you really know how to read, tbh.
