Your sources, from wherever you have cherry picked them, are wrong from a medical point of view because you quote them out of context. I have studied human physiology over the years for my professional training and I know. Human body, irrespective of gender, can be trained to do any kind of physical activity as needed. All your nonsense talk about testosterone and estrogen does not make an iota of difference, simply because you dont know how they work. Heck you dont even know what they exactly are!! So chill out on the noise you are generating. And no matter how much hulla bulla you want to raise, the fact remains that with proper training, a fit woman can do the job needed. Period.
You pulling out random numbers like less than 1% or more than 10% is simply malarkey. Its like pseudo intellectuals saying that humans normally use only 10% of their brains (totally false BTW) leaving the remaining untapped!!
Emphasis is on training, a soldier in combat will take any well trained individual (male or female) as a partner, over a foul mouthing, weakling of a pu$$y...
There is nothing leftist or feminist about this view point. IA is not stupid to recruit weaklings. Anyone who can make the cut physically, can and will be recruited- color, religion, caste, gender dont matter. If you dont know, there are many female F-15/F18/F16 pilots in USAF/USN who have dropped munitions in Iraq and Afghanistan.
Its the likes of you who hold back the development of the society steeped in their neo-conservative, chauvinistic, misogynist like ideals! You have your view point. Noted. Doesnt mean its the absolute truth.
