A vote for Jill Stein, Cornel West, Oliver Chase, or not voting, is a vote for Trump. Palestinian lives don't matter to Trump, nor do they really matter to Harris; however in general, Harris will be better for Americans than Trump, so vote for Harris.

Just as a vote for Nader was a vote for Bush.
Imagine if Nader didn't run. Imagine there was no Green Party candidate for US President.
Gore would have probably won, and America would have been the better for it. Probably no Iraq war, maybe not even a 911. As a result Iran probably wouldn't be as strong, and Putin probably would have less to legitimately oppose about the US, and would himself be seen as less legitimate—indeed Ukraine might still be whole today.
A new Green deal would probably be in full swing.
Granted, Harris doesn't really care about Palestinians, and some elements of the Democratic party care even less; but Trump cares even less than Harris, and what he will do to the US will be worse.
So while Israel massacres civilians and steals more land, at least under Harris American women would still more easily get abortions, we will have fewer TGs committing suicide (maybe), and health care will be a little more universal.
Also with the 100% tariff on Chinese EVs, the Big 3 will be able to better produce good inexpensive cars (as they've been at least somewhat intending these past several decades), and fascism will have less of a hold on the US.
Therefore: vote for Harris.
If you are a progressive: vote for Harris.
If you are an environmentalist: vote for Harris.
If you are a libertarian: vote for Harris.
If you support voting reforms such as proportional representation, rank balloting, the abolition of the Electoral College, and/or more political diversity: vote for Harris.
If you are nauseated at the idea of voting for Harris: take a barf bag with you while you vote for Harris.
If you are a Palestinian-American who has a relative who was injured, maimed, or even murdered, in Gaza, you should still vote for Harris, because again, Trump doesn't care about them either, but at least you, as an American citizen, will get a better deal Harris than under Trump.
(I'm not entirely sure if I agree with all the above, but I find it hard to refute.)
Then the effect balances out. They should try being appealing to voters instead of using the threat of "the other guy" in a hopeless race to the bottom.
