The point isn't to run down the female soldiers or the job they are doing. Many are doing very well. We may very well be able to field an all-female army and still beat the snot out of the Arabs, who only seem to be brave and powerful with a bound, helpless victim.
The problem is that there was never a good reason to put women near combat in the first place. It was a political stunt. It is pushed and promoted by feminists who have not the slightest inclination to serve themselves.
For all of recorded history, with scarce exception the deal has been women staying home with the children while men fight. This is practical. How many empty slots do commanders have to fill that women have purposefully vacated through pregnancy?
"Oh," you say, "that isn't fair to the thousands of women who do faithfully serve." No, but the point of an army is not to deal out fairness or conduct a social experiment.
I used to share most of the views you outlined in your post. But in the last few years my views have changed a lot -- based on the things I've read and some of the great female soldiers I've met and worked with.
