It seems like the authors directly contradict that. There's the section I quoted, but they also just don't talk about anything that women will do as a gender class to tear down the gender class system. Some antifeminist communists pay lip service to feminism by saying "of course we're feminist, women are part of the revolutionary proletariat". As you pointed out, the "totality" stuff is pretty tacked on and the bulk of the specifics are about how gender accelerationism is going to bring about gender abolition.
