While I think JKR might have been a little too drastic, and that there can be solutions to make both trans and non trans people happy, I would have never attacked her that way, because I understand her concern that a solution based exclusively on the gender felt by anyone, if implemented not enough carefully, could undermine some biological females rights and even their safety. Examples have been made about men being allowed by a new clumsy law to access changing rooms and anti-violence shelters (that anyway must exist also for trans people, as they too are very often victims of violence) for women, but it just took me a few minutes to find another serious danger:
If self declared genre is made the only legally valid one, biological women could lose the right to have the same job opportunities, as the most ruthless employers could be tempted to fill all female workplaces with females that cannot get pregnant in a totally legal way. And non trans men claiming to feel women could undermine trans people rights too this way.
Anyhow, I understand that even in the worst case scenario, trans people aren't by any means the danger for women, the real danger would be a law that allow any man, even with bad intentions, to be legally considered a woman just claiming it.
