The biggest argument against women in the military tends to be that *on average* women tend to have less physical strength or endurance then men, and there may be some truth to that fact. However, this completely ignores the fact that militaries across the world have hiring standards which include physical fitness. The only people allowed to enter the military are the ones who meet those fitness requirements, regardless of their sex or gender. It might be true that, on average, a randomly chosen women off the street would be less likely to meet those requirements then a man, but that doesn't really matter because our military is not made up of people randomly pulled off the street. All that matters is how fit a women actually serving in the military is, and if those women had to pass the same fitness requirements as men then they should be expected to be just as fit as the males they serve with.
By contrast there are, without a doubt, women who not only meet but surpass the fitness standards of most militaries. So why should such a women, who is physically more fit then men actively serving in the military right now, be told she is unfit just because there exist other women who are not as fit? Should we not judge the fitness of a soldier based off of their own, personal and demonstrable, physical fitness rather then based off of some statistical average that includes a bunch of folks who will never try, or succeed, to enter the military?
