I heard that somewhere too.Yes the word holiday didn't come from holly, but maybe there's a correlation with "Hollywood" and the holly tree and witchcraft. I really don't know, but that's what I've heard.
Not all Jews believe that. The ones that are in the entertainment industry / Hollywood generally are. There's a documentary on it where Jewish rabbis of various denominations are interviewed and admit to the books that they use. Unfortunately, none of them believe the Bible, but think it's fictional.I've heard about the Cabalists. But that's not all Jews right? I mean, I know that the Jewish religion is basically antiChrist cuz they reject Jesus, but I know someone who tends to lump Jews in general as evil people who do diabolical horrible acts. And there's a lot of people on free speech platforms that do that too.
