I tried to explain this near the time of the event, back when I was on reddit. For this I received mass downvoting, and a universal consensus that misgendering is perfectly appropriate as long as the target has done something evil. Even from trans people. “We don’t claim her!”
It would be one thing if these same people also misgendered any given cis person who did wrong. But they don’t, and that double standard is transphobia. “Of course I would never misgender Hitler. He was AMAB. He earned it. You’re not AMAB? Then your right to be a man is contingent on your behavior. I’ll decide if you’ve been good enough to deserve it.”
We’ve got a long way to go culturally before people recognize that there is literally one and only one valid criterion for entitlement to a certain gender identity: claiming it.
But you have to understand, to 74 million people, the Fox News Cinematic Universe is reality. There’s regular bullshit, and then there’s bullshit so widely believed that you actually have to study the bullshit, just to be able to predict what its subscribers will do next. Like religion.
