I'm not going to put a thought towards helping Palestine now because the people who advocated for it stabbed everyone else in the back. No solidarity for us from them, no solidarity for them from us. I'm not going to ally with someone who actively fucked over everyone in a bid that had no chance of winning them anything. That's not how political allyship works. They can go fuck themselves. Furthermore, even if I wasn't this bitter, it wouldn't matter because there's literally nothing I can do now.
Edit: you're probably going to say something stupid like them not being a significant part of the electorate. Doesn't matter. Elections are made of thousands of decisions, and each one against Harris was one that contributed. The blame is shared.
