Oh believe me I am the first to criticize PC madness if they are sub standard kick them out through the armed forces predefined process. But if you DO find some that can do the job then what is the problem?
Most women are mothers and all are daughters and it's for that reason that they want to serve their country in this way (concern for family and country is a good reason to join up?). Making a killing in the private sector is a vocation, serving in the military is a calling and an honor in my own limited opinion.
If the woman is in a non-combat role then it is no problem.
The problem is deluding ourselves into thinking that women and men are not different and that combat is a social experiment.
How long do you think a 'all women fire-dept, police dept or military would survive?
So, the women who are getting into these professions are being shielded from their own weakeness of being women by the fact that there is a majority of men around them.
