Jim,
I agree that using an apples to apples comparison to sexualizing for male and female roles is true. Males have never been as sexualized compared to Females. The problem I am seeing with your viewpoint over men issues is that you seem to assume that male issues is over being overpostive or a dream standard that most men can not achieve. While that argument itself is not invalid, you fail horribly in finding negative roles for men in gaming.
Men are disposable. The disposablity of men are such a normal thing, that we are just numb at seeing it. In the GCN game 'Geist' there is a part of the game where you kill a soldier near a computer. If you actually read the computer, it will be a letter to his wife on how he will be home. If that letter didn't exist, you wouldn't care that you killed that soldier. You wouldn't care that he died, yet now that you gain the knowledge that you just killed a loving husband, how do you feel? Remorse? Sadness? Regret? All irrelevant.
In video games, you are told to kill waves and waves of men with no back-story, no reasons to exist but to die by your hand. Even NPC's that you work with can be just as disposable. Your comrades may die in the game, and unless he is your best friend, you are not given a reason to care. His existence is to be no more than a cold body on the floor and reinforce your need to kill for vengeance.
A man's life is of lesser value than a woman's life. I highly doubt in the current culture you can debate that idea. Sure you can say both men and women are equal in their value of life, but that's not how video games or any media treats it. If you were given an option to kill 10 men or save 1 woman, what would you choose? Is a woman's life more valuable then those ten men?
I will even go back to just using women as sexual objects. In games, women have a place, but their deaths are something to ponder before chopping their head off. In many games, women are not killed off in some shameless or useless reason to reinforce killing, most of the time their death has a value. You can and will find examples to prove the opposite to what I just said, but most games do not use women's death in the same manner as men.
Jim, the points you have are good but they don't even drill far into the iceberg of sexual roles and negative contexts of those roles.
