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.

Yeah, the global promille is of course the main problem.
How well JKR fits that group is another thing: you don't jump from an unemployed single mother into the lizard illuminati, no matter how well your books sell as films.
That's partly why her actions are so easy to identify as toxic: she doesn't have the [connections/experiences/generational status] to work behind the scenes, like the Koch and Ellison brothers, to name just four.
