The best way to "fix it" is to point out how doomed the Jewish race is. Aside from Arab Jews in Israel (who are looked down upon by the ruling caste Ashkenazi), Jews are undergoing what they are calling a "silent holocaust". Basically, cultural decay (which is often blamed on Jews) has affected Jewish individuals the most and they are outbreeding at completely unsustainable rates; not to mention low birth rates as well. So.. mechanisms described as "white genocide" are affecting Jews even harder.

Which leads to the crux of the conversation, ask them if snapping your fingers and making all Jews vanish would actually fix any problems. Is the cultural decay actually something tangibly created by one group? Or is it a greater entropic decay that is actually much harder to fix than just removing a perceived pathogen?

Furthermore, Jews need to understand that they need to change their approach to treating others. They have been considered unsavory by virtually every culture and race on Earth- at a certain point some introspection is warranted. You cannot create communities with your own policing and hospitals and expect everyone to look at you as equals, just ask anyone from Brooklyn or New Jersey how they feel about this. You cannot create an ethnostate and expect outsiders to trust you. So another issue here is optics and overall behavior.
