this is a pathetically stupid argument you're making
yes, there are machines that allow women to do jobs that men can do. a woman can operate a forklift just like a man. then next time you move, instead hiring movers, rent a forklift if you feel the need to
Or maybe if I'm unconscious in a burning building, and the average female fire fighter can't pick my limp body up, should she just call ahead for a forklift or the jaws of life?
and no, women cannot fight just as long as men can and just as hard as men can, but because you seem to love living in a nice, oblivious place, i'll spell it out for you why:
1) upon completion of basic training, the average male can throw a grenade 40 yards, and a female can throw it 15 yards. a grenade's blast radius is about 15 yards
2) women have lower bone density, and a statistically significant portion of women fail to complete basic training because of stress fractures that come from heavy physical exertion
3) a statistically significant portion of women are combat ineffective during their periods
and while israel may conscript women, they rarely, if ever, serve on front line duty
