Wow, that's really horrible. Of course they have grounds to be offended and take action. Why would anyone do that? It seems really silly. It's not even creative or funny. I really don't understand why she would think that is okay in the workplace. I work in a very small company that has pretty loose rules, and nobody would think to talk to each other like that. I sincerely hope the employees win.
I agree that there are gender inequalities that put males at a disadvantage, and it's totally acceptable for people to voice their complaints and seek change. I guess an easy example is the draft. I don't see why young women wouldn't be eligible as well. We aren't made of porcelain. There are places in the world where both males and females are required to serve in the military. Some other issues are: child custody/divorce battles, male rape victims (lack of support systems for them to come forward), and increased incarceration time for males vs females. However, the existence of these problems doesn't cancel out any women's issues. They're just different.
On the video game character power fantasy/sexualization:
While I think the male power fantasy in video games isn't the same problem as the hyper-sexualization of females in video games, it's still problematic. Although, I will say that there tends to be more variety for male characters. For example, there are sexy male characters in many JRPGs. Then there's Catherine. That dude is just ugly (great game though). The GTA, L.A. Noire, and Heavy Rain protagonists don't seem to fit the stereotypical definition of attractiveness either. While you have the meaty/simple-minded men of Gears of War, Call of Duty, and God of War, there are also a lot of pretty complex male characters out there (Silent Hill 2, The Last of Us, and most games listed above). However, it does seem like many of the top-selling games suggest that men are at their best when they're murdering people with their 20" diameter biceps and talking in a gravely voice about "doin' what needs to be dun."
So I would say that what the medium many times says about what males should do or act like is problematic.
On the female side, it just seems like a different problem; in most cases I don't even feel like I'm playing out a power fantasy (mine anyway) as a female protagonist. Bayonetta is the only game that comes to mind where the female sexualization is (successfully) part a power fantasy. Fighting games like Dead or Alive, Mortal Combat, and Soul Caliber were particularly bad in this respect; I did not find these scantily clad females very empowering. I tended to play as the most appropriately dressed female character from each game (or just play as guys), even if I liked the fighting style less. The jiggle physics are just too ridiculous. Anyway, the best you can typically hope for in females is being pretty, but maybe has an appropriate amount of clothing on. Most are at least easy on the eyes, and too many female characters tend to fall flat. Even though I loved Heavy Rain, the only disappointing playable character was the female. She lacked depth and seemed to be there mostly so she could take care of the man, have the sex, and get into a lot of strange near-rape situations. The best counter examples to this I can think of are Gone Home, Portal, and old Metroid games. Still, many games tend to suggest that females are at their best when they look sexy still manage to kick ass (either in physical prowess or some secondary, supportive function). Or not. Either way.
For females, the medium says that females should look a certain way regardless of their actions which is also problematic, but different from the male problem.
