Well, I'm not sure that characterization is completely accurate. Unless I'm missing something (and please tell me if I am) he watched someone do a proposed celebration dance that contained anti-semitic tropes and he laughed and said he'd do that in a game.
Which, to me, is different than outright saying something anti-semitic. It could just be that Puca is kinda dumb, or unpolished dealing with the media, or naive and got himself caught up in the moment. (Speaking from experience I've only gained in the last ten years, people who are Mormon are often ridiculously naive about other religions. Like, jaw-droppingly so) Not a good look, but I think characterizing it accurately is important.
