Men can give up their legal rights to a child and not pay support. It's harder in some states then others, but it does happen. Most men, I've found, do not want to give up full rights. They just don't want to pay support, and that's where the problem lies. When faced with the real meaning of giving up full rights, men would rather pay the support then do it. The difference for a man and woman in that regards, the mom can struggle to get rights back, the father cannot.
War is profitable. Not to you, yourself, but to the big names that write the big checks come election time. I'm not a no war theorist. I think there are good reasons to go to war. I fear that America tends to go to war for the wrong reasons. I.e. people like to talk about Hitler and WW2, the problem is, we joined the war because japan bombed us. Not really because, hey, the Nazi army was killing thousands of people. Sure, we helped there too... however, we didn't go full force until we had some fires going. On the flip side, we charged right into Iraq with little proof other then a man on the tv telling us we were in danger.
Women aren't going to be added to the draft because no congressman is going to risk loosing all that support. Same reason women are going to be put on the front lines. Somewhere, in the us, it has been rationalized that a woman in a body bag means a lot more then a man in a body bag. If it was her choice to put herself in that war or not. Let's just face that fact. It's not going to happen no matter how much we all argue.
