I think there's a large problem between people who don't know whether they should be fighting for equity or equality. Sometimes, people tend to assume gender equity can only be achieved through equality, which means that we have to assume that both genders are equal despite all evidence to the contrary. (Hence, some people pouncing on "studies" that validate the absence of human sexual dimorphism in things such as muscle mass)
It's not even something people are willing to approach in academia. Studying the correlations or linkages between something like race and physical attributes is ethically repugnant to the modern enlightened mindset and will eventually lead to people screaming "eugenics!" in a suitably high-strung manner. Which is why we have to assume that say - an average Japanese woman will be as capable as an American one in a basketball competition. Humans always get "special case" exceptions, and as a biologist, I've been trained "not to go there". It's much easier to deal with organisms with fewer strong opinions
From a human perspective, I think Greer has a point - the biggest enemy of modern women is other women. Let's say Ms Sarkeesian has an issue with the portrayal of women in video games since the industry is largely male-dominated. If we want to acknowledge this divisive kind of thinking, the onus of action is then on women to make video games catered to female interest, not for males to either insert token women in some affirmative action movement (trying to forcibly change the market to something which hasn't been proven to exist) or to try to "write for women", because that'd just be the male idea of what they think vocal and soi-disant disenfranchised women want.
Men might have sex and power fantasies - so what? I never see Ms Sarkeesian without lipstick on (male-created enabler of female subjugation to the ideal of a sexualised male fantasy). She needs to find what archetype she thinks ALL women should all neatly fit into and get them to all agree with her. Good luck with that.
Edit: And if I'll say something sexist here: The main problem with male gamer reactions with regard to Ms Sarkeesian is that the constructive male approach towards female bitching about issues is to try to solve all the woman's problems. I personally find that women largely bitch because they want catharsis, not because they want to actually *do* anything about it.
Besides, she could make a video entirely of footage of cats, I think it'll get less than 800 posts going "WTF".
