I'm absolutely voting for Biden and everyone should, because he is the best viable candidate on literally every issue, including Palestine.

That said, he has openly and loudly taken Israel's side for months. As a result, he's made himself an avatar for all the other US institutions that are openly against any criticism of Israel or support for Palestinians. Even if he has secretly been doing everything he can to stop the killing all this time—which I doubt—he had still fucked up massively when it come to avoiding the blowback from other groups' attempts to crush anyone who speaks out, including agencies his administration controls.
