I don't want to align with people shouting 'jihad'."

Yes, or with the IR. Many of us feel this way. Many Jews are very defensive of Israel b/c of generational trauma so pls be patient with us. We are working on this within our communities. Any many anti-zionists are being useful idiots for the murderous IR. If you're writing letters and giving money, those are usually things done in private and should be fine. Those are good things to do.
