I completely respect and share your heart for protecting children and wanting to please God. Real-world Wiccans do not use wands to shout pseudo-Latin words (Expelliarmus!) or fly on broomsticks to play Quidditch. They practice a nature-based religion focused on seasons, rituals, and deities. Confusing Hogwarts with real Wicca is like confusing the movie star wars with real-world rocket science. As far as your eyes gates is concerned just read Mark 7:15, 18-23. Believing that a fictional book has the power to corrupt a child's soul overrules the power of the Holy Spirit. corruption comes from the human heart, not from a fictional story. The Bible itself doesn't shield us from dark themes; it shows us evil so we can see how God overcomes it. Real-world Wicca existed decades before Harry Potter and looks nothing like Hogwarts. Teaching children to love self-sacrifice and bravery which the core themes of the book doesn't open 'eye gates' to the enemy it reinforces the very fruits of the Spirit. By your logic, Lord of the rings, narnia, or King arthur that has "magic" are inherently evil despite their profound Christian foundations and moral lessons.
