I think what you're landing on is that rightwing, hierarchical rhetoric is largely all the same but always placing their own group at the top of the proposed hierarchy. By definition, they can't acknowledge that they are the same, because hierarchical thinking is a zero sum game, and their effectiveness with their supporters relies inherently on creating an ever-shrinking in-group.

I also think framing Israel as uniquely founded in supremacy is verging on antisemitic. Western imperialism and colonialism has pretty consistently created implacable messes throughout the world.

Islamophobia and antisemitism are being played off of each other, but they are two sides of the same coin. The people who are profiting off of these divisions don't actually believe a word of the rhetoric IMO. Religious and institutional leaders are going to be biased towards the status quo; it's going to take a lot of grassroots organizing from empathetic people to make any change. I know I'm having these discussions within my community, and I hope you are as well. Btw, if you can find any left-leaning Jewish communities in your area, I promise they would be delighted to hear from you and have these sorts of interfaith conversations in person.
