I don't get this whole drama with Harry Potter. When I was younger, I was a big fan of Ender's Game. A few years later it came out that the author of the Ender books was a huge bigot and was using his money to promote right-wing causes. I dropped the books, didn't buy anything else from the author, and every other fan of the series that I talked to did the same. There wasn't really any debate about it. When the movie came out, none of the fans of the books showed up and so it flopped.
With Harry Potter, though, it's been years since we found out what kind of person J. K. Rowling is and people are still whinging about it. Why is this still even a debate (outside of right-wing transphobic circles, of course)? Find some other books to be a fan of.
