Sorry, I have to rant here: Is US American left stupid? Your civil rights are being demolished, your friends, colleagues, comrades are being detained and deported, social services are being dismantled and your fragile democracy is being replaced by dictatorship - but your take is that under Harris Palestinians would have been killed as well. Same difference? You can not tell me with a straight face that the fate of Palestinians would be the same under Trump and Harris.
On the other hand this might just be a coping mechanism: you could have prevented Trump but now have to live with your decision and the reality that he didn't stop the wars he promised...
