Anyone who's getting *****y at you for holding the door for them is a wingnut. They don't represent the main face of the feminist movement. Being a nice guy shouldn't get you treated like that. If it has happened to you, then I'm shocked. Otherwise, it just sounds like a stupid anti-feminist talking point.
There might be jobs females are physically less capable of then men, but I wouldn't go so far as to think they are incapable. If you'd seen some of the females going through SERE with me, rucking around 60 lbs a day for 13 hours at least through the mountains, you'd think differently. Women in combat is an entirely other matter though. If she can pick up a gun, point it at an insurgent, and shoot, I'd be happy to be alongside them. Hell, first USAF casualty in Iraq was a female enlisted security forces airman running convoy security, which is damn close to combat these days.
And now for my asshole bit...most women who want to go into dangerous professions have a pretty good understanding of the dangers they face. The above-mentioned security forces, female Marines (not infantry obviously, but still folks on the ground in Iraq, like the interpreters I went to DLI with), and most other high-risk military positions are good examples. It's not up to you to decide what's better for them and disallow them from a job based on its risks.
On the same point, if a female in the military chooses to become a mother, the military gives them the option to either be discharged or continue in their job, their choice. I know a fair amount of people like that.
EDIT: Dammit, GB, stop it, I'm trying to post here! Got stopped twice because of your posts
