Our voting system is “first past the post”, this means there are mathematical realities that are not ideal.
We live in a world with entrenched powers that take advantage of this voting system to maintain power. The fact of the matter is, third party candidates have little chance of winning in a normal situation, when it gets as heated and tribal as it is now, there’s no realistic chance of ONE third party candidate pulling enough votes to win the election. The result of this is diluting votes for the major two candidates. The one with more diluted votes loses.
I don’t like Biden, I don’t like Democrats, but I’m not going to risk a Trump presidency (which will undoubtedly be even worse, I mean, you don’t think that the guy that moved the embassy to Jerusalem is gonna end the genocide do you?) by voting third party.
If you want this to change, push for voting system reforms, there are mathematically superior systems out there (proportional representation, ranked choice, etc), we just need the political will to change the law, but too many people on the left-ish have become convinced that accelerationism and willingness to put others at risk for ideological purity is the righteous position.
Let me be clear, the righteous position NEVER involves harming innocent people or putting innocent people at risk.
We are trapped in this system, the way out is to bust the trap, not ignore it and expect to win.
The difference is we can’t predict the next ten years let alone the next century, so to assume our heinous actions can be cancelled out by some potential future that makes it all worth it is simply a silly argument. You’re betting the lives and well being of others that we win. There is no guarantee a revolution results in successful, sustainable communism. It’s quite likely a revolution results in millions of dead, massive environmental damage, and a generation with PTSD, only to result in fascism.
