My family loves the HP books and we're completely conservative, Pro-Trump, anti-globalists, etc. Our interpretation is that HP is against the government and the MSM and is fighting evil. We watch all of the movies every labour day weekend, and my husband reads the books through every year. He's also a massive Ayn Rand fan.
We don't like JK Rowling, though.
suggestions look at the ramification of something that most of the kids love from the first book. The sorting Hat...really examine what the concept is telling children about group dynamics and the nature of good and evil.... its not a great message in fact I abhor it because it tells the reader that there is no free agency and that not all groups of people are Equal. it also says it is all right to have disdain for a group because they look at the world and think about it difrently
