He’s a secular leftist Jew. Secular leftists are religious oriented, but they hate the obligations of their religion.
They are dedicated to the left, because they see the opportunity for salvation by mandating a perfect world.
This way, in their minds, they can say to the Messiah, “Look what we have done and why we deserve salvation. We fed the poor. We took care of the sick. And all that.”
To which the Messiah will tell them, “I never knew you.”
He’s not a Jew. Being Jewish is passed down from the MOTHER, who in his case, was Irish Catholic.
