JK Rowling. Everyone used to have a very favourable opinion of her. I remember when the media would worship every tweet she made, as though she brought about world peace. Then she became obsessively transphobic and now that's all people think of when they think of her as a person. At first, I gave her the benefit of the doubt and thought it might be a misunderstanding. But then she went out of her way to make sure everybody knows how transphobic she is. It's become her whole personality. Even Elon Musk, whose own child stopped talking to him because of his transphobia, told Rowling to knock it off because she was harping on transgender issues too much.
