They (in particular groups like AIPAC) prefer to reject the opinions of actual Jewish people outside Israel in favor of working with local extremist groups. Israeli far right jews frequently call other jews “antijewish” just for calling for peace. And Nazi types love to help them out. Groups like jews for peace gets ignored because nobody supports them publicly, and Nazi types gets protected by right wing politicians like Republicans.
The only thing they have in common is that all those groups are totalitarian authoritarians, with similar obsessions about Israel’s borders. You’d think those extremists would have a bit more survival instinct - but who am I kidding, if you have brains and common sense you don’t become that kind of extremist…
And as usual it’s a problem because conservatives funnel money to hate groups like this, in all countries
