It doesn't matter if a woman can pass the physical, or if she can carry you on the beach, if she's a better pilot than you, or can kick your ass in hand-to-hand combat. Shield maidens!
This is the argument the left wants, that some women are more capable than some men, because they know it's an argument they will win.
It's an utterly irrelevant argument.
Why does our military exist? At it's core, to protect our way of life. When two dissimilar cultures go to war, their militaries are expressions of their cultures. The more successful culture will win and thrive. The inferior culture will either learn or will either and die.
Our culture, our western culture, or American culture, has many tremendous values that have made us the most successful people in the history of humanity. We respect the individual, we foster creativity, we reward intelligence coupled with hard work, and our men protect our women and children.
Why do our men protect our women and children? Because cultures that cherish and protect their women and children defeated those that didn't. Protecting women and children, may seem common sense, but it is actually a unique and defining aspect of our culture, that our military exists to defend.
Putting our women, our pregnant women, in harm's way... what exactly are we fighting to protect?
Really though this just hurts recruitment of those men you actually want in your military. How likely are you to want to enlist and go off to war when you have no idea what kind of people you are going to be serving with?
The military will by completely full of desperate people that need whatever bonuses they are offering and diversity hires that want to play soldier in no time. Everyone else will go fuck that shit and make other life choices.
They will probably be so desperate for recruits they will probably start recruiting criminals in prison.
Another excellent point!
