As is Rowling's. It actually hurts. I'm not sure why it's somehow a point of humour that I'd have an emotional reaction to all this. Firstly, after all, it has an impact on me personally; secondly, I rather enjoyed Harry Potter growing up; and, thirdly, even aside from my personal connection, I care about other transgender people and hope that they can feel accepted, and respected, and not in some sense have to feel either shameful, or in some sense constantly apologetic for their own existence or desire to be an active part of society.
So, yes, at times I might get a little tetchy. So. What? It's not a strength to be emotionally detached all the time, and it's not a strength to mock other people emotionally reacting.
