Agree completely.
I would like to add how in addition of something being harmful, there's also *identifying* something as harmful to us/community/society/etc. AND being in a position to do something about it.
Is Rowling more harmful than petrol cars (for society, community/environment)? Certainly not, but it's easier to opt out from Rowling, and not buying books is legal unlike blowing oil pipes.

At the same time I would hope people would ne reasonable with their dislikes. Sometimes these things get separated from their roots and start living their own life.
See: shit piled upon the non-binary author SenLinYu for having written a story that started its life as a Harry Potter -fanfiction. Rowling didn't get a cent from that, and in general I do think it's a good thing when characters gain indepdence from their creators.

Also there's something to be said how copyright is de facto assumed to cover scenarios, character names or characterisation, etc. It doesn't. And trademark is about first-party marketing, not content or way-of-mouth.
But this is separate topic.
