I'd argue women (and men) are already told what they can and cannot do with their bodies. For instance you're not allowed to sell it or put certain narcotic substances in it. I should be able to sell one of my kidneys....but the government says I can't do that with my own body. 

and..your argument might be stronger if women didn't realize that having sex can lead to pregnancy. But it's hard to plead ignorance on that. Men only get one choice after conception: pay child support or go to jail. 

Men shouldn't be forced to be a father just because they had sex. That doesn't mean they can tell a woman what to do with regards to her body if they get her pregnant, but they could declare they want no part (financial or otherwise) and be free of the obligation after conception. 

There is numerous cases of men committing suicide because family courts are overwhelmingly in the woman's favour.  Stories in the National Post this week. Sorry globe for saying talking about your competitor ;)
