IDK about the person you’re responding to, but

who actually lives there or who practices the religion.

There are a lot of Jews that don’t fit into either of those categories. Ethnic and cultural Jewish people that don’t practice or believe in Judaism as a religion are very common. I call myself Jewish, because my mother and my grandmother are Jewish, but I don’t practice the religion. I’d recommend googling Jewish Atheism and Jewish Secularism for more info.
