Compelling argument but,
If any developer used Sarah Palin as influence for their protagonist, in a non-humorous way i mean, that would be my end of this great hobby/vice i've had since 2nd grade.
I am by no means sexist but I use videogames like so many other people do, as a way to satisfy the demands of my lower brain! So I EXPECT a little Sex, Violence, Shooting, Stabbings, Punching, Get my mind off of myself and onto this new badass Duke Nukem esque Axel inspired character with Commander Shepherd elements so I can disconnect for a bit and get on with my life tommarow, Throwing, Kicking and Screaming in my videogames! Preferably all at the same time! With more EXPLO-SHEE-ONS!!
Games satisfy the (mostly but not all)male needs of Conflict and Competition which stems from our base behavior which is also related to Sexism among other isms that I don't feel like getting into right now. While I admire your will to fight in this case these things have been talked about before and if anyone really wanted them it would have been changed long ago.
After a long day at work, you know what? I kinda like the illusion that I can solve all of my problems not by thinking about them, but by just WALKING DOWN THE STREET AND BEATING THE CRAP OUT OF ANYONE LOOKING AT ME! (I reference Final Fight and Streets of Rage but really that's gotta be at least 90% of all games ever made)
