So she is a feminist. Feminism = equalism
If feminism actually meant equality then radical feminism would logically mean the most radical form of equality. But as we know, that's not the case.
I don't think you're wrong in saying radical feminism = radical equality, but I do think that you see radical equality differently from what some see it as. I personally see "radical equality" as not only equality, but a way to almost counterbalance the scales. For Jim-Crow era laws, radical equality might mean giving blacks 5/3 of a vote (something that has been argued); for Jews, that might mean carving a country out of the Middle East; for feminism, that might mean making women almost a superior class.
Not that I think that is the correct thing to do, but for me "radical equality" means giving the "oppressed" more rights than the "oppressors" and forcing the "oppressors" into the former position of the "oppressed".
That sounds like punishing some people for the sins of other people in the past, and giving extra benefits to people today who didn't earn it, because of things that happened to similar people in the past. That will only perpetuate a cycle of victims and oppressors, because the new victims will then want their revenge when given the chance to become the oppressors and create another new class of victims and so on and so on.
