Just as the Women's Rights Movement ended up simply a suffrage movement. For similar reasons: for women, the right to vote and the right to determine whether we bear children are the rights 'with which we secure all the others.' And if you don't think so, look at how the birth dearth in Europe and Japan has helped maintain funding that helps parents.
This narrowing has not been the choice of the feminists (except some pandering Democrats) but the single-issue focus has weakened us in both cases, not because the position is not a fundamentally important one, but because single-issue movements eventually lose the point of a movement. In the case of abortion it has been made a defensive battle, rather than simply a part of a new way we want to live--which includes a lot better contraceptives (free, of course, along with all other health care), men who wear condoms and don't whine about it (or 'forget'), morning after pill over the counter, sex education that actually teaches about sex, etc. etc.
I don't think you can blame feminists primarily for this defensive focus--it's hard to be wholesided and continue to give good answers while they're shooting at you. Sometimes you just feel like letting 'em have all six. But I think it's worth noting that force, ultimately, is always required to prevent women from having abortions, once we know that they're possible. And even before, if the conditions are bad enough; women enslaved in the Caribbean killed their babies on birth rather than see them enslaved.

No, it goes: Against abortion? Get a vasectomy.

Women are engaged in a struggle to be while we're also those who create other beings--the conditions of creation are in the hands of the workers themselves, whether we think that's proper or whether we think the 'violence' of liberation struggles or abortion happens to be justified. I do.
