You can't just legalize abortion and expect the whole issue of unwanted children to go away. You will also need to provide very extensive sex education coupled with free contraception. Prevention is better cure, but not having a back-up plan(abortion) is equally short-sighted.

The main group of women who will benefit from having access to (free or subsidized) abortion are the ones who are poor and/or have no family support. This is the same group who would find contraceptives expensive/inaccessible and find themselves lacking in sex-ed.

Also, make other birth-control methods for women more accessible(IUD, depo shots etc), gives women more control over their own bodies and not be at the mercy of the man.

Long story short, legalize abortion, make sure its accessible to the poor too, but first and foremost improve sex-ed and access to contraceptives.

Exactly man, whenever people yell 'Abortion = murder', the first thing that comes to mind is how much of a hypocrite they are. They'll save a fetus to soothe their conscience, but what about afterwards when baby is born? You fellas want to chip in your time, money and emotions to adopt the baby you just saved? What about education/food/shelter/love for the next 18 years?
