There may be more that care than you realize by reading these threads. I have refrained from voicing my opinion on the Potter books and movie after seeing how polarized the opinions are on both sides of the issue. There doesn't seem to be much hope of persuading those on either side of the issue to change their minds.
My view on this boils down to this: it is a conflict between rival religions. I am a Christian, and I have a problem with my children reading books that promote and glorify a rival religion. To those who claim that the Potter books are non-religious, I can only say that the practices that are used by the characters (good and evil) in the books are strongly condemned in the Bible, because they involve worship of and service to other gods. Remember the first commandment: "Thou shall have no other gods before Me".
I encourage the study of other religions and practices so that I can be better informed when talking to those that practice them, but I draw the line when there are fictional materials that use entertainment to draw readers and viewers into the world of a rival religion.
Is it asking too much for those who see no problem with these Potter materials to respect my views and refrain from hurling insults? I can take it, but I don't think it helps your credibility.
Here are a few examples:

Mary Poppins trashed your fragile life eh? Oh the pain… You and the Taliban sadly have much in common.
Could you point out the parts where Harry and co. worship and offer service to any gods at all? I must have missed those bits when I read the books. Chapter will suffice, you don't need to go so far as page number.
