Nobody is actually saying an ethnostate is ONLY wrong when it's Jewish, though. The people who protest what Israel does to Palestinians also oppose Turkish and Syrian ethno-statism by supporting the anti-ethnostate project in Rojava, by speaking out against what China does to Tibet, by supporting the end of British rule in Northern Ireland. and joining the liberation cause of Black, Brown, and Indigenous people in the U.S. There's essentially nobody who protests against what Israel does to Palestinians but says nothing about the misdeeds of other ethnostates.
