JC2:
I just think that when a woman is already pregnant, presumably in the majority of cases because a man has had consensual sex with her knowing that there was a chance she could become pregnant, it's too late for him to be legally allowed to walk away and say to hell with her. The baby is already on the way. Too late. Should have worn a condom or had a wank instead of having sex.
Having an abortion is not something that should even be on the table unless the woman chooses to put it there. The ability to have an abortion is not a default position that anyone should assume that any woman can/should take. It's not like a waste disposal that she can flick on for her or anyone else's convenience. It's a *controversial surgical procedure that many, many women would NEVER even consider undergoing unless there was some life-threatening reason for doing so. I don't think that you can glibly say "well that's her choice, then". Not having an abortion is hardly a "choice" for someone who would be haunted to their grave if they ever did so (whether for religious, moral or ethical reasons).
I know you'll say that it's the woman's choice to raise the child without his financial support, but if she can't have an abortion, it's not a choice, is it? And I don't think it's overstating anything to say that an abortion is not a choice for many women.
I think you're overestimating the instances of women using pregnancy as a way of trapping a man into supporting a child they don't want as some kind of lifestyle choice. You know, in many cases of accidental pregnancy the single mothers didn't want to have a child either, it was a distaster for their life too, but it was the only thing they could do given that they were already pregnant and felt some responsibility to deal with it and make the best of it. In comparison to the impact that raising a child for 18 years has on the life of a single mother, I think the father is actually not doing too badly if he just has to help a little bit financially. I'd be all for him being involved as a father and having a say in decisions, for the child's sake, and he should have a legal right to do so, but he shouldn't be just allowed to say "oh, that was rotten luck for you, see ya" and walk away. No way.
The only exception to that I can imagine to that which would be fair would be if the couple made some kind of legally binding agreement before having sex that the man would not be responsible for a child resulting from an accidental pregnancy, but of course in practice that isn't gonna happen.
I agree with everyone who is emphasising sex education. It still amazes me that any adult has sex without knowing that even with contraception, the woman can become pregnant.
* when I say controversial, I mean that a vast number of women, including those who are pro-choice, find the idea of abortion utterly repugnant and would never be able to end a pregnancy by choice
