Here is the piece that summarizes the evidence. Miers voted for loosening performance requirements for firefighters so that women could qualify. It's also claimed that she and Alberto Gonzales were responsible for watering down the stand Ted Olson wanted to take in opposition to preferences in the U of Michigan case.

If true, between this, her lack of judicial experience, and failure to ever take a strong position on anything except how important lawyers are to our society, there is more than enough reason to object to her nomination. The White House should be embarrassed to have claimed that a woman who needs a crash course in constitutional law is the best-qualified person that it could find.

Actually this is someones opinion of why the requirements were revised. It appears to apply to promotion of rank once women (or small men) were already on the fire department.
Let's presume (for argument sake) that the height/weight requirements were 5'8" and 150 pounds to be a captain. This would be discriminatory not only to women, but small men (some races are known to be smaller than others.) Captains are basically administrators. Why can't a small man or woman act as an efficient "pencil pusher?" I don't know the facts of the case, do you? What were the particular arguments. Let's see a post on her opinion...not a post by someone else telling us to presume what her opinion was.
