Yeah, considering how the Uk doesn't really have free speech, and put a child iirc on house arrest (?) for a year because she reposted a video from the US and quoted what it said (got punished because she wasn't the race in the video and wasn't allowed to say what they said)
if she was really this terrible person doing all these terrible thing the UK would have locked her up and brought up numerous charges. UK officials are quick to do that, unless the people who dislike Rowling believe that ONLY she is exempt and officials won't do anything because she has secret plants inside that spare here and ONLY her from local regulation.
I find that very hard to believe.
