A thing I hear a lot is how the Harry Potter series is very important to people, it got them through difficult times, it holds a special place in their heart, etc. and like yes of course. It was a super popular book series aimed at young people. Having emotional attachment to it

is normal and it doesn't make you a bad person but look: Rowling is a powerful person actively harming marginalized people with her rhetoric and your personal attachment to her books don't take precedence over the people who she's harmed speaking out against her

It's not meant to make you feel bad about your own history or what the books mean to you but also you maybe need to consider not taking up space in the conversation if all you're going to do is demand reassurance

Like I said. We all have relationships with problematic media because we're not born knowing how to critically consume things. But your relationship w/that media is yours and something you can think about without derailing the conversation
