Yes it would be better. My Name is Ms Tree, let me be your tour guide to reality. The optimum out come is not always ways what happens. Contraceptives fail, accidents happen, heat of the moment happens.
As Dog pointed out above, the republicans not only do not care about that and make every effort to block anything that would prevent unwanted pregnancy such as sex ed, contraceptives, family planning. The republican idea of birth control is just say no. Like that works so well. Just ask Sarah Palin, Bristol Palin and Track Palin how saying no worked.
It boggles the mind how republicans can be against abortion and also be against everything everything that would help prevent unwanted pregnancy. That has got to be the dumbest set of positions I have ever heard. It's like being on the Titanic and not liking life boats.
