I guess the difference for you as opposed to those of us who think this discussion is a good thing, is that some of us don't necessarily think this particular subject has been brought up 12 times. Yes, the subject of religion has come up before, but not the demonization of people who read Harry Potter books. (At least not that I've seen, anyway.) For me, this is a fresh subject that deserves a look see.
I noted on another thread that someone was surprised that people still burn books. If people are surprised by this, it means that the word isn't getting out enough, and we need to talk about it some more.
