That is very bold of you to tell transgender persons that they MUST accept hateful words directed at them. Once again you speak from a standpoint of privilege. You cannot speak for other people and it is certainly not fair for you suggest someone is less of an 'ADULT' because they view art in a different way due to their very valid feelings, please stop being so insensitive. J K Rowling has done lots of charity work yes, but so did Jimmy Saville and I am sure you won't rush to defend him in any format. Charity work does not make you a good person.
If certain people want to feel uncomfortable with the Harry Potter books because of the tarnish that Rowling has placed on them with her awful views then so be it, they are perfectly justified to feel this way.
