HBO put out a preemptive statement about how they are happy to have JKR involved on the show (she owns all the rights lol), basically telling the trannies to sack up and deal with her presence.

There was also some crazy Lefty who said that the child actors who will be playing the main trio should be ready for the harassment they'll face due to their choice to work with Rowling, essentially threatening children. You will need a lot of popcorn.
