Again. This is not how this works.
Stein isn't taking Trump voters. She's a Left-Wing distraction candidate. In some systems, like RCV or Proportional Representation, her candidacy wouldn't hurt the Dem as long as voters were thoughtful with their votes. But in FPTP, which we have here, she's definitely a threat. We're bitterly divided here, to the tune of close to 51% wanting lefties and 49% wanting righties. All she needs to do to throw this election to the Right is poach 3% plus whatever Right-Wing third party candidates there are. Since the Right is unifying behind the Shitgibbon, it's real easy for her to spoil the election and get all 51% who want progressive and/or liberal policies to get conservative policies instead. This is even worse when you realise Conservatives have gone Fascist.
The only reason Jill Stein has a chance to spoil this election is because we've got a large and rabid minority of voters who actually like what Trump is serving. If Trump were down 10 points in the Swing State polls, Jill Stein's 1% wouldn't matter. If Harris had 270 EVs worth of locked in states, Stein could take double digit vote counts in places like Oklahoma and California and still be a non-factor. But in this closely divided of an election, with the political system the USA has, your purity crusade will result in possibly the last election you ever get to vote in, and at minimum, 4 years of policy that will utterly destroy every priority you have.
And do you really think cutting support for Israel will gain more votes for Harris than it loses from people who happen to think Israel has a right to exist and a right to defend itself? Here's a hint. It won't. First, we are certain you'll just find some other reason not to vote for Harris, and second, it'll piss off moderate and conservative Jews and run them straight into the Republican's arms. According to this article, there are somewhere around 3.6 million Jews nation-wide who vote for Democrats. In 2016, only 1.4 million people nation-wide voted for Jill Stein. If you only turned off half the Jewish vote while capturing every Stein voter there is, you'd still have a net negative, and I'm absolutely sure AIPAC would go apeshit over this (and they support Republicans too), and Stein voters would just find another reason they couldn't possibly vote for the Democrats.
So, if you are really dumb enough to think a protest vote is a good idea, know that your meaningless protest will cost LGBTQ and minorities and non-Christians and women HERE in this country dearly, while doing absolutely nothing to help the Palestinians. It'll also fuck the Ukrainians over, and maybe even the Taiwanese, as I can see the Shitgibbon leaving them to China's tender mercies. Muslim voters who back Stein over Harris will own-goal themselves as they'll be the first to be attacked by Project 2025 and Trumps Mass Deportation/"Remigration" plans. LGBTQ, Minority, and women Third Party voters will also bring their doom, while White, Male, and passable-as-Christian Third Party voters will benefit from their privilege but best get down to being Good Americans because the Trump Goon Squads will be set loose looking for Leftist rabble to round up.
