Another lesson for the day but first I have noted your qualification of Judaism i.e. "is tribal in the sense".<quoted text>
Judaism is tribal in the sense that it believes that the specific laws of Judaism are meant only for the nation of Israel.
Lesson, Judaism is a RELIGION it is NOT a TRIBE and it has NEVER been a TRIBE. There are no TRIBES called Judaism.
Explain the nation of Israel concept that you speak of.
