Well unlike you suggest, I don't vote blue no matter who, I vote blue because the other choice is demonstrably worse.

I'm sure the party cares deeply about this justification, since that seems to be all they're running on these days.

I remember back in 1984 when such a strategy was considered comical:

    It comes from a very ancient democracy, you see..."
    "You mean, it comes from a world of lizards?"
    "No," said Ford, who by this time was a little more rational and coherent than he had been, having finally had the coffee forced down him, "nothing so simple. Nothing anything like so straightforward. On its world, the people are people. The leaders are lizards. The people hate the lizards and the lizards rule the people."
    "Odd," said Arthur, "I thought you said it was a democracy."
    "I did," said Ford. "It is."
    "So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't people get rid of the lizards?"
    "It honestly doesn't occur to them," said Ford. "They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates to the government they want."
    "You mean they actually vote for the lizards?"
    "Oh yes," said Ford with a shrug, "of course."
    "But," said Arthur, going for the big one again, "why?"
    "Because if they didn't vote for a lizard," said Ford, "the wrong lizard might get in. Got any gin?"

You wax eloquent about how things need to change and so you choose to do nothing

Says the guy who thinks that repeatedly voting in a game that was rigged from the start isn't "doing the same thing over and over while expecting a different result".

what happens when you recruit enough lefties to your side that the right is able to establish the equivalent of a dictatorship via voter suppression, coups, etc?

Non-fascists will be forced to accept that working within a system that's designed to disenfranchise them can never produce a democratic government and join with the anti-fascists. The dictatorship is subsequently overthrown by popular action at the cost of many lives (which likely includes my own as a nonbinary person with left-wing politics). This creates space for a second constitutional convention to fundamentally reform the law of the land.

At that point you are 100% fucked.

We've been 100% fucked for longer than you've been alive, the only question is whether or not you're comfortable with the current rate of fuckery and what you're willing to risk to change it.

Are you one of these idiots who actively want a civil war?

Lol, of course not. I have merely accepted that nothing short of a second American Revolution could overthrow the two-party system and that things will definitely get worse before they can get better.

Hell, I predicted this way back in November 2016. Trump's win would galvanize the Democrats in 2020, and the subsequent lack of meaningful change depresses the vote enough that 2022 and 2024 go to the republicans. Trump then punishes his percieved enemies while the Democrats continue to chase Republican voters to the right, further fracturing their own left-wing base.
