Rowling has a pretty good idea. She's chosen her side. She outed Dumbledore as a homosexual (in a speech after all the books were finished and had sold millions) for a reason. Trump is against globalism and open borders. If you know the books for House Elves read immigrants. It's the same old liberal story, any exclusion from anyplace or anything is hateful and bigoted, therefore all seven billion people have a right to move to any country they'd like.
It's insane but it's the prevailing view among Oxford educated traitors like Rowling.
Trump might turn Hogwarts Academy into the clubhouse for his latest creation, the Harry Potter Links.
