Seems like this is just people making up a "problem".
There ARE games out there that deal with sixism. It's far from unheard of. TES games have never dealt with it, however. There's no evidence that they want to wade into the issues of sixism. There's no evidence that "political correctness" forced them to change the design of their game. Past games had plenty of strong females doing all manner of things. (Evidence would require links to interviews that comments were supposedly made)
Seems more like this thread has a problem with extreme anti-political correctness, where some people think something is wrong if sixism or the like isn't prevelant in a game. That's pretty messed up.
That said, the game does deal with racism somewhat, regarding the Stormcloaks.
Agreed, while equal rights are a necessary and important part of democracy, gender roles should still be encouraged along with moderate social conservatism, but were starting to go a bit off topic here .

Off-topic, but science doesn't support this point of view at all. Specific gender roles, beyond the biologically obvious (women get pregnant, briastfeed, etc) are always shown to be enforced by a culture and upbringing rather than being necessary or part of a gender's intrinsic makeup. Studies show that women lean away from math and math-based careers not because they aren't good at math, but because even in elementry school they pickup on social cues that women aren't "supposed" to do that. I shudder at the thought of how many potentially great scientists we've lost to this as well as the loss to other fields.
I see no reason why a game should have sixism as a strong element just because YOU think it should.
