I think a lot of us trans girls are in the same situation. I learned to read on HP books, and Hermoine was a deeply important character to me growing up 😅 It’s hard for me, but I have gradually moved away from the series as it increasingly becomes associated with Britain’s Top Transphobe.
I think the moral arguments aside, there is just the practical matter that having read what he did, I cannot stomach to consume content made by him. The association is naturally aversive, I don’t need a rational argument about how it’s immoral to support a rapist - I just don’t like it.
