This has got to be the greatest load of horse shit I've seen in quite a while. Just because you're stronger than most women (and maybe even most men for all I know) doesn't mean a woman can't do most of the jobs that you can do. And some jobs they will do better than you. You might have a steroid-enhanced physique that makes you look (and act) like the Hulk! But just try soldering a delicate component onto a circuit board in a field repair and see how well your strength helps. Need to haul a deuce-and-a-half up a hill? Great, grab a pile of muscle-bound jocks and have them haul their hearts out. OR you can grab a power-winch and let Twiggy do the job a lot faster.
As for women in combat, I suggest you rethink! Just look at the Israeli Army. They've had women in combat units for decades, and they can fight just as well and just as hard and just as long as any of the men. Sure, there may be situations where brute strength works best. And there are situations where being small, quick and quiet will work better. BOTH kinds of soldiers are needed, working as teams.
It's this kind of thinking, that women are less than men, that make women targets in society. They aren't looked upon as real people but as property, to be used at the whim of the man. If you treat women as equals, and really understand, deep down, that they are equals, you and they will be far better off. Give women the respect they deserve, the same kind of respect you think YOU deserve. They've earned it.
