Doing Gender

I find West and Zimmerman's arguments about gender to be compelling and generally true. Good for them for taking the time to create definitions and argue about the ways in which we "do" gender. While I agreed with their arguments, I did have one problem with this article. Actually, it's an issue I have with many of the articles about gender. Why is it that all of these articles are obsessed about all the ways in which we do fall into our gender roles and worry very little about the ways we defy these expectations? Why are we so obsessed with defining our genders? Is it possible that if we stopped trying to define gender we would have an easier time dealing with gender?
These are just the questions that run through my head as I read articles like West and Zimmerman's. In the end I feel that they make points that are extremely important to the balancing of the genders. I just wish that in that balance we were able to better include individuals who don't fit into traditional categories more easily. The effect of gender roles on these individuals may seem pretty obvious but I feel that it is still important to consider these various types of gender representations when defining sex and gender.
