Pretty sure I never suggested that being cisgender, white, or rich is as wrong as being a transphobe, this was merely an explanation of her abundant privilege in those areas. I mention her wealth because she is largely sheltered from the real world, and has apparently only ever experienced transness from the perspective of trans exclusionists like Maya Forstater, whose contract was not renewed because she was found to be harassing trans folks on a Twitter account connected to her work email.
Rowling does not march for us even though we are discriminated against for being trans every single day. She does not march for the trans women of color being murdered so regularly. Instead, she writes long diatribes invalidating our identities while pretending to be worried about trans men, all while misgendering and reducing them to their parts.
She may paint flowery words to appear vaguely supportive while never actually standing beside us in solidarity — her actions are very much against us.
