I think we agree more than this exchange might suggest. My core point has never been that the left is blameless. It's that there's a meaningful difference between a party feeling electoral pressure on Israel policy versus a party being captured by antisemitic ideology. The former is happening with Democrats more so in recent times. The latter is what's happening on the right, and the two aren't comparable in scope or depth. That's my core point.
I'll note here that your hope that a new Israeli government brings Democrats back does suggest that the break between the two, at the governing party level at least, is really about policy, not prejudice, and that's a distinction I've been wanting to draw all along.
