It's nothing to do with it. It's not about opposing Israel's actions being wrong. It's that both parties support Isreal blindly. And the gop, specifically trump, are significantly worse. So when voting, it makes no logical sense for that issue to factor against choosing democrats vs republicans.
Yes, this is in the past, but there are (hopefully) more elections in the future. It's very important that people get out and vote for the only viable alternative to the horrors that are the gop these days. People who didn't vote for democrats last cycle need to wake the fuck up, recognize that they are responsible for the current disaster, feel the guilt for what they did, and change.
It seems that you agree on that, since you voted dem last time, but you still are throwing shots about how democrats shouldn't be elected. And that's pragmatically dangerous.
