The absolute worst is Margaret Atwood.
She knows. Everyone knows she knows. The wrote THE book about female oppression.
She made a fairly mild comment about not being allowed to say what a woman is or something along those lines, and was immediately attacked by trans activists.
She could have said, "Oh, I recognise this. This is authoritarianism. I don't like authoritarianism. The Handmaid's Tale is about that as well as female oppression. This is a fundamental women's rights issue, as well as a free speech issue. Now I understand what JK Rowling is talking about."
Instead, she looked at how healthy her bank balance now is thanks to her super trendy collaboration with Hulu, and how relevant she had become in her 80s, and recanted.
