OK, so your argument though does presuppose that these two viewpoints are necessarily conflicting. I would say that they are not. Again, the worker/CEO and woman/man dichotomies are not intersecting. There is a separate solution to both "problems" simultaneously (not saying you'll LIKE the solution, merely that one exists).
Now, because a single decision (the hiring of this woman) has both helped the worker/CEO gap, and harmed the man/female gap, it gives the impression that the issues are irreconcilable or intertwined, but it would be quite possible (again, not saying it should be done) to reconcile both disparities independently and simultaneously.
In other words, I think you are conflating two distinct issues because they happen to overlap here.
Your argument would have some teeth, I think, if you could show that:
1) Liberals are more interested in equalizing pay by any means rather than increasing the quality of life of the worker class.
and more importantly -
2) this newfound CEO wage will stay where it is after this woman is gone and a man becomes CEO again. If it doesn't stay where it is, GM isn't "sensitive toward the women issue," GM is an opportunistic fuckstain :)
