If you convince everyone who cares about Gaza not to vote, then the parties absolutely cannot afford to have a pro Gaza stance, because it’s electoral suicide - all the people who care about Gaza don’t vote and will the people who just hate on Muslims so.

I convince people to vote for anti-genocide parties like PSL and the Greens.

Not voting, voting for Shill Stein, it's all gonna have the same effect - republicans winning and the democrats chasing the only votes on the table because the left folks abstain or effectively abstain.

Not supporting Palestine is electoral suicide.

Not voting is electoral death. Voting third party is electoral death. On which planet is the republicans winning going to make the democrats move away from rightwing policies? None of them!

If the dems don’t want leftist votes and move to the right,

They are going to move to the right if they lose. We have one of the most leftwing candidates the democrats have fielded in decades, and if she loses, the party bosses are going to say "see, it's senseless chasing leftwing votes, they're too pure to muddy their hands in actually effecting the outcome - we have to more to where people who actually vote are. The only way to win is to have policies that actual voters like, not your theoretical voters who won't compromise - you'll never get their vote. Come back to the centre!" And of course we both know what the centre means in America.
