I.e. that people often don’t have deep insight into the creators of the art they are enjoying, so considering liking Harry Potter as a statement about their feelings on the author doesn’t resonate with me

Which is fair, but then the same people get offended when you try to educate them. It’s the same debate every time a new Harry Potter medium is announced. At this point, you must be living under a rock if you are a Harry Potter fan and have never heard of the controversy that surrounds JKR.

I think most people don’t know about JKR because they don’t want to know. They are afraid that when they dig deeper, they will have to let go of their favorite franchise, so they choose denial and ignorance instead. It’s hard to give people the benefit of the doubt when a topic has been discussed so many times for so many years.
