I’m not completely bought into your comparison, but running with it for a second — If one were to challenge the notion that the Japanese state should privilege ethnic Japanese over other people living in its borders, no I would not consider that position to be “anti-Japanese”.

Similarly, I don’t understand is how expressing the personal view that all of the people living in the territory of Israel — Jews and non-Jews alike — would be better off living in a secular state, is somehow akin to anti-semitism.
