Stop using the prefix "Ultra" as if it signifies something.
The rabbi is an Orthodox Jew. Period. If he is not a Jew, then who is ?
And the entire history of the "Jews" and their connection to modern-day "Israel" is a Myth.
There is no evidence of "expulsion" in 70 AD. Zippo.
The majority of today's "Jews" are descended from the Khazars, a Turko-Mongoloid people who converted en-masse to Judaism in the 8th/9th Century AD. They have NO connection to Palestine.
https://en.wikipedia.org/wiki/Khazars#JudaismThese people then moved north into Russia, and later into Poland, etc, from where the majority of the world's "Jews" trace their ancestry. NOT Palestine.
Zionists hated Orthodox Jews, and modelled themselves on European Nationalists, including the Nazis.
The Nazis even struck a medal celebrating their pact, with a swastika on one side and the Star of David on the other...
Later, during the Second World War, once they had got a foothold in Palestine, an extreme Zionist group (Lehi, the political ancestor of Likud) literally begged the Nazis to form a "totalitarian" alliance against the British in Palestine.
In 1948, Einstein compared these people - who were by now in power in Israel - to the Nazis...
