Just ranting or was there an argument against something specific? What you're stating here is exactly what has been referred to ad nauseum when stating the government can discriminate if it can be determined without exception that females will be able to perform adequately in the roles being assigned. Since every service and even among services the physical demands of the MOS/rates are quite different I imagine mileage will vary. Me personally, I say open the doors, set standardized non-biased physical requirements and see who signs up and makes the cut. If that number just so happens to include zero females nobody could argue they weren't offered the opportunity.
