You’re right. The people who put their principles above Palestinian lives aren’t left wing. They’re centrists. An actual leftist puts helping others first. Voting Democrat reduces the harm that others suffer. Abstaining does nothing to help anyone. But there are some people who will choose to let brown people in the middle east die, when they could have easily prevented it, if it means they get to have clean hands and avoid some kind of misplaced guilt. They think for some reason that a vote equals a bomb, and that choosing to be a centrist means opting out of responsibility for their government’s actions. They think they can live all alone in their white middle class suburban bubble. That their inaction means they can’t have any of the blame laid at their feet. They pay taxes to the US government, which uses the taxes to buy bombs to kill Palestinians, and these centrists think that choosing not to take responsibility for how their tax dollars are spent makes them guiltless. And that taking on a guilty conscience by accepting responsibility, is a bigger price to pay than genocide and war.
