Since “Superman” was created by a couple of Jewish kids from Cleveland, that makes him Jewish. Raised in a small town by a “Goyisha” couple, he probably never knew. Also, they didn’t have a Synagogue in town, so he probably wasn’t Bar-Mitzvah’d. It’s doubtful that he was Circumscised. The foreskin of the superbaby would’ve been impossible to cut! What a mess!
