Abortions were not legalised up to 24 weeks for women however young or old to have up to 24 weeks to decide if they wanted to have a baby or not. There becomes a time when its not about womens rights but the rights of the life inside her.
Abortions were legalised so women that were not mentally capable, medically well or that had a sick baby growing inside them had the option to make the heartbreaking decision to end their pregnancy.

It was not legalised as a form of birth control or so people would stop passing judgement on the women who sort to make that choice for themselves.

I believe women have a choice up until a certain point. Then I say "Suck It Up" the time to make a choice has passed.
