Hate to rain on the parades of people who think that a woman can physically do what a man can do, but how often do you see a woman do a man's job like carpenter or electrician or laborer in the real world where time is money? Ain't gonna happen. Well, there are those one in a thousand exceptions, but those are exceptions.
By the same account, not all men can serve in the military to standard. As a young Lieutenant, I had to have a soldier reclassified because he couldn't pick up the 94lb shell we fired from the cannon. So your argument there is flawed.
Now do you really believe there are as many men who can't pick up an object of a certain weight as there are women who can't pick up that weight? When it comes to the military why not hire the best and have the men do men's work and women doing women's work? Used to be that way. Waves, Wacs. WM's etc. Look it up sometime, back when men were men, women were women, and people knew there was a difference. In the meantime, go visit a gym sometime and compare the weights that men lift compared to what the women lift.
