I would add that there ARE things you can do to help stop the genocide, that are not refusing to vote. I absolutely believe that the demonstrations, protest votes, calls to congresspeople, and so on, are part of what’s behind the changes to the US’s Israel policy recently (sanctions on settlers, pause in the weapons shipments, stuff like that - that’s nowhere near enough and no excuse for Biden’s support for Israel during the “war” and before it, but also, nothing ANYWHERE near that has happened in 75 years of consistently war-criminal support by the US for Israel).

All that stuff makes a difference and can help stop the genocide. Refusing to vote does nothing to stop the genocide and risks putting someone in office who is much much worse (actively wants to kill more Palestinians.)
