I understand where you’re coming from, but respectfully, I disagree with how effective it would be. If telling somebody that their actions will lead to a Trump victory and explaining how much worse that will be not only for Palestinians but for Americans doesn’t convince them to choose the lesser of two evils, nothing short of replacing Biden in the next election will work.
Skepticism runs really deep in the current political climate, and even if Biden changed his mind tomorrow and withdrew support, those voters are still going to distrust the motives behind it. For all they believe, it’s an election year, and Biden is just making an empty promise to stay in power. He could easily turn around and resume support once he regains his position, and they’re not going to trust that he won’t when they “know” he was more than happy to support their genocide before he got in trouble for it.
That’s not to say I am supporting Biden or apologizing for his actions. I’m right there with you when it comes to trying to demonstrate my dislike for his handling of the conflict, but I’m also voicing my concerns that whatever election cycle Trump is participating in isn’t the time to practice a hard line stance on voting third party to express your dislike of both the Republican and Democratic candidates.
