Was talking to a lawyer.

For the sake of dispelling confusion, error or deception and for promoting truth and honesty:

The rightful and lawful Judahites and other Israelites were of the Hebrew faith. That was their religion rather than "Judaism". AFAIK, mention or promotion of "Judaism" is lacking in the Pentateuch/OT/NT/Bible. Judah was of Israel but was not all of Israel. AFAIK Judah was never by the one named at Exodus 3:14 encouraged to create its own, separate religion or doctrine from that of the Hebrew faith. AFAIK Judah wasn't given any eternal power of attorney for all of Israel. If anyone can find contrary in the Pentateuch or Bible or OT or w/e..they can post the specifics.

Was there then also Reubenism, Simeon-ism, Levi-iism, Issachar-ism, and Zebulun-ism? And even Manasseh-ism and Ephraim-ism? Or even Israel-ism, Dan-ism or Benjamin-ism?

THE SCEPTER DEPARTED FROM JUDAH ~4AD

The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be. Gen. 49:10 (KJV)

The departing of the scepter already happened and is a matter of solid historical record (even Rabbinical writings).

THE BIRTHRIGHT WENT TO JOSEPH RATHER THAN JUDAH!
Furthermore, the significance of Joseph ought be kept in mind: Reuben lost his position as firstborn. The scepter went to Judah but departed from Judah at a time when Jesus arrived on the scene (as prophecies by Israel). Though salvation was and may still be said to be of the Judah (the true ecclesia continuing that 'administration'), the birthright was given to Joseph (1 Chronicles 5:1-2).

Now the sons of Reuben the firstborn of Israel, (for he was the firstborn; but forasmuch as he defiled his father's bed, his birthright was given unto the sons of Joseph the son of Israel: and the genealogy is not to be reckoned after the birthright. For Judah prevailed above his brethren, and of him came the chief ruler; but the birthright was Joseph's: ) 1 Chronicles 5:1-2

Judah was given a specific authority or duty for a time. However, the birthright was given to Joseph rather than to Judah.

ANOTHER BIRTHRIGHT ISSUE
The birthright of the firstborn of Israel was given to Joseph. Judah was given administrative authority for a time. Of course, another birthright of issue is the one being meted out right before our eyes between Essau/Edom and Israel. The right of the firstborn of Isaac is AFAIK to go ultimately to Israel--it is in fact with Israel (rather than with Essau/Edom) but yet fully apparent to the world. But the right of the firstborn of Israel is to go to Joseph.

• Right of firstborn of Abraham: Ishmael (spiritually) disqualified, vests in Isaac.
• Right of firstborn of Issac: Essau firstborn, 'diverted' to Jacob, reverted to Esau for a period, to vest in Israel.
• Right of firstborn of Israel: taken from Reuben, given to Joseph.
• Judah: prevailed over his brethren, held scepter until the time it departed ~4AD.

Note: Esau took Ishmaelite and Canaanite wives (the Canaanites settled at the area around Mt. Hermon. The connection to the Fallen Angels and the oath they took may related to the admonition against Hebrews and Israelites marrying Canaanites).
