The people who loudly object to the books have never read them. They heard the word "wizard" and freaked out, and at least the ones I have talked to refuse to read even a paragraph, because they're positive it'll corrupt their sole, and possibly even that the books are the direct work of Satan, which is why everyone who has dared read has been blinded to the evil, or something. (The same person who said most of that to me also claimed that Buddha taught his followers to worship Satan. We're not talking rational debate here.)
