Is it true that Harry Potter is jewish?
Harry Potter is a fictional character (although he is real – inside our heads), and therefore there is no real answer to that question. It would be unfortunate if he was, because ????? ?? ???? would pretty much bring his adventures to a short end. He is certainly not religious, which is evident from many many places in the story. So many that I won’t bother bringing any.
You are probably talking about the actor, Daniel Radcliffe. Who has absolutely nothing to do with our thread, because we are absolutely discussing the Book Series, not the films, which are a terrible portrayal of a brilliant saga.
