Whether or not an ethnostate is good depends on the ethnicity of the people of the ethnostate.
(/s, it is POV of a racist)
Gosh why do people hate the Jews so much. 🫤
The problem with ethno-states is that it makes it super easy for people like yourself to conflate ethnicity with nationality.
People don't hate the Jews, people hate ethno-states who are currently committing a genocide. Many of these people who hate the state of Israel for their genocide are Jews themselves.
