Why do Christians bristle at Harry Potter and astrology? Competing magic is a no-no.
You seem to be less familiar with Christians than I am. Here's a report of a legal case that I was involved in personally of a Christian patient of mine who refused to work Harry Potter night at her library.Huh? I know of no Christian that thinks like that.
Harry Potter is a big no-no with plenty of Christians. Odd that you wouldn't know that.
