She created a false narrative that Linus was encouraging "physical intimidation and violence". She purposefully took a joke out of context to push her agenda. She seems to be trying to create a situation where it impossible to disagree with her, else you're some kind of "abuser", whether it be a racist or misogynist. Why? I don't know but I wouldn't be surprised if she was seeking a position of power where she could govern the moral rules over a large project and assimilate everyone into her monoculture by calling everyone who disobeyed her rules racist or sexist or what-have-you.
Whoah... Step back a bit. Let's say, for the sake of argument, that the joke was taken out of context. Going from that to knowing what her motivations are is a huge stretch. Isn't it possible that she sincerely believed (even if you disagree) that changes were necessary and would be beneficial?
The stuff you mentioned above is a really flimsy basis for accusing her of an agenda of trying to impose a monoculture, however you may couch that accusation in words like "seems to be trying" and "I don't know but I wouldn't be surprised if".
