I know she publicly condemned a Scottish bill recently (I think it was called Gender Reaffirming or something to that effect.)
The bill would have made it much easier for people to legally change their sex on their birth certificate, basically withdrawing the requirement for medical diagnosis to do so. As is my understanding
I could see her donating to the campaign/s against said proposed bill. But I can’t find enough information to draw a conclusion either way.
The bill was ultimately not passed and I suspect people are eager to attribute that largely to Rowling’s vocal (and possible monetary) condemnation.
I don’t know if I would agree with that assessment. But in saying that, it’s also a bit hard to see what exactly she has donated to specifically. I can find her vocal criticism or support for various legislation much easier.
Maybe there are laws against political donations being public knowledge in the UK? Or maybe such information is just buried under all the years worth of controversies. Or maybe she donated to the campaigns under false names for easy plausible deniability in the long run. Idk.
But I have seen her vocal and monetary support for various anti trans bills come up quite a bit. So I’m a little eager to know the specifics myself.
Just a bit hard to find right now with the game controversy blowing up everywhere
