I don't accept the delay or the other lawsuits as evidence that she's lying. As a man who has quit two jobs due to sexual harrassment (once by a man, one by a woman) the only way I would talk about it openly is if there were supporting claims made by others. I certainly wouldn't expect to win any cases as things are now.
Is her language unreasonable and problematic? Of course it is. Punch someone in the face and see how civilised they are after that. You treat people badly, they don't often stay polite.
