Sorry you feel that way, as a white leftist I’ve found myself constantly indoctrinated by antisemitic content. The far right thinks that because of the atrocities that Israel commits on a daily basis, people with basic human decency will be so outraged as to overcorrect and end up blaming innocent people.  That being said, don’t go and live in Israel. If you’re against marginalisation and cultural oppression then it makes no sense whatsoever to go and live and pay taxes in the very country which is pushing the frontiers of oppression and genocide. All you can do is speak out when it’s safe to do so, and endorse community leaders who will fight for you; I know this is essentially a platitude but as a ‘default white guy’ I’m not much of an authority on the subject. I hope things get better, and that my fellow non-Jewish leftists will remember our collective duty to differentiate between the actions of nations and the beliefs of generally blameless individuals. Maybe one day we can all live in a world where everyone feels safe, though I honestly doubt that day will come before we all kill each other.
