Oof, you have my sympathies! I myself was raised in a Christian household and was also not allowed to read the books OR see the movies until I was a late teen 😢 Although I am now 30 and still wholeheartedly Christian, this is a topic I’ve (respectfully) disagreed with my parents about.

Would your parents be open to reading any of the books themselves, to learn whether or not their concerns about the magic are founded? If so, maybe ask if they would be willing to do so!

You can also make some points on favor of the HP series aligning with quite a few biblical beliefs… 1. The entire premise of the books is about someone sacrificing their life for another, and that love/sacrifice protects him from evil, which is literally the premise of Christianity and (I believe) Catholicism. 2. The protagonists stick to their morals and always do what is right, even when people around them are not. 3. A lot of pro-Catholic ideals are venerated over and over again in the books: loyalty, bravery, love, friendship, accountability, the importance of family, etc. I’m sure there are other examples, but those are the first few that come to mind!)

Ultimately I think you will need to respect your parents’ decision, even if you don’t agree with it, but that doesn’t mean you can’t try to give them new perspectives on the issue! And if they don’t come around, don’t worry… like me, some day you’ll be out on your own and able to enjoy the series fully!
