Yes, that is very true. However, we have the freedom to try to help her realize the value of NOT choosing abortion. Freedom means the possibility of choosing incorrectly but with that incorrect choice will come the consequences that direct us to the correct choice, sooner or later. Our progress depends upon each of us freely learning the lessons of life and then correctly applying them.
An important consideration here is whether or not there has been sufficient progress in this human experience to have the privilege of freedom of choice - we restrict that privilege from children until they display the maturity to exercise reasonable choices. It may be that our pregnant women do not have the maturity or moral development to rate the freedom to decide this question. Then those who think they do have that development can force their will on them. Not me, thanks.
Abortion is a form of homicide, it is not a lifestyle choice, such as deciding whether or not to smoke or drink. The state has a duty to protect innocent human life. This is not a question of whether pregnant women are mature enough or not to understand the consequences of abortion although some clearly are not. It is question of whether or not we as a nation will continue to allow an entire class of human beings to be classified as unworthy of the protection of the law.
