No, trust me, you don't; there's a good reason for your parents' caution. In case you didn't already know, Harry Potter is about wizards and dark magic, and although some might argue that it's not just dark magic ("There's light magic too and it combats the dark!"), wizardry and witchcraft is against the Bible. To be honest, Harry Potter is a wizard/sorcerer/ warlock, which is a male witch.
So trust me, you don't want to read it, haha.
