How come people haven't accepted Potteranity and instead rely on the tenants of Christianity?

I have been worshiping for a week now, and I honestly can't tell the difference from when I used to worship Jesus Christ back in the day. Harry Potter wants all his loyal followers in the great halls of Hogwarts. He has come to me in a vision while I was asleep. He said if I spread the word of his great wizardly powers, he would grant me head master of Hogwarts, and allow all those who seek his loving guidance, all will be welcomed as a student for all eternity to learn and bask in the great hall. He has instructed J. K. Rowling to write of him, and his many great deeds to save humanity. Harry has been reborn for your salvation. He wants your love and devotion, he wants you to adhere to the laws of wand usage, so that you use your power for good and not evil. Why do many people shun him as their only hope for redemption?
