You're right, there was a "just" missing there: "an ethnoreligious group, not just a religion". Though the religion is properly called Judaism, not Jewishness.

That said, seems we're nitpicking on details. Judaism is a religion for one people, it doesn't seek converts, and the good overlap between the ethnic group and the religion (actual or claimed by the Jews themselves) is the basis for the idea of a right to a "return" to the historical land of Israel.
