I'm sorry, I put that badly.
I am not suggesting it is anyone's choice but yours to get pregnant, or that anyone else can make that choice for you.
The posts I was responding to, however, weren't about pregnancy, they were about whether it's ok to say that every social disadvantage women (specifically mothers) face is their own problem because they 'chose' to have a child.
I don't believe this is fair, because that choice to have a child also has inescapable and very basic implications for the rest of society.
I'm a little confused as to what in my posts made you think I wasn't suggesting society should be looking after children already here? 
Narked put is so much better than me so I will quote: 'If you start treating the birth of babies as essential to society rather than a women's issue then you solve a lot of problems.'
I would argue that denying women access to contraception etc is making it a 'woman's issue' because it is focussing on taking away her rights, not on looking after her as a person and then, if it comes, her child as a person).
I think this is true that making it not a 'woman's issue' is also better from an environmentalist point of view, since at the moment I think the motivations for having/not having children are so screwed up with women's poverty (which is huge), women's status and women's rights over their own bodies, it's hard for the environmental arguments to get any look in. But I could be wrong here, it's just a hunch.
