(Posting this not because "my opinions are so important", but because I saw many people saying that "no one here supports JK Rowling.)
Because she has courage.
I don't agree with her on everything. But I'd rather have someone who doesn't agree with me, but who has courage, than a pathetic coward who agrees with me on everything. How bad would that make me look?
I feel the same way about Roger Waters. Like Paul Joseph Watson said:
You have to respect Roger Waters. Don't agree with him on a lot, but he could have safely retired with his massive pile of money and had a quiet life. Instead, he's 79 and is still a constant irritant to the regime. Few such cases. source
Be an irritant to the regime.
I don't support Rowling but that doesn't mean I'm antagonistic towards her. She's in the bracket of 'she's annoying at times but really useful at pissing off my enemies'. Her work resulting in the Hogwarts Legacy debacle that has done more to move the anti trans sentiment than ANY detransitioner (because the media silences them quickly) is evidence of that.
But I put her with all TERFs as 'useful but not to be given a pass' as a lot of their earlier pushes is why we are in the state we are in now. I'm just hoping the leftist civil war happens so willing to hold fire for now, especially since the other side are VERY open about their pedophilia...
