Unsure

I've been considering giving away my Harry Potter books and movies ever since I learned that J.K. Rowling is anti-trans. But the thing is that I bought the books from a used book store before Harvey destroyed it, meaning that the author doesn't get the money, only the store did. However, I bought the movies from online and regular stores like wal-mart, sam goody, and walden bookstore before I that one fact about J.K. Rowling.

So what should I do? Should I keep them and live the guilt but get to enjoy them? Or give them up and never have relive the adventures over and over again but will have a clear conscience?
