@Murraygoldberg If you are considering contacting her, just do it!
I felt compelled to email JKR's office after seeing the abuse she got after the 'people who menstruate' tweet, having never done anything like that before and got a response thanking me for my support.
She is such an inspiring woman and I really hope that getting emails and letters of support and thanks helps in some way to offset the vile threats and abuse that get sent to her. I thanked her for her books (I'm a Robert Galbraith fan, my kids love HP) as well as for her standing up for women and girls when others don't. I love that she has kept going with bringing this issue to a wider audience.
