Agreed. And Justices David Souter and RBG agreed as well. There are other Const. rights that could have been used. It was a poorly crafted decision that was focused on one aspect...an important aspect...of abortion. But still only that one thing:
RvW specifically decided that states may not ban the safer medical procedure of elective abortion. The procedure was safer than pregnancy/childbirth and they found that women had the right to choose the safer procedure. They also referred to the 9th A in the RvW decision. It's no different than a right to have consensual sex, a right to reproduce, or a right to travel from state to state. It's accorded to the people unless there are reasons to restrict or ban it. (hint: so no one 'invented it'...they just protect it unless there are reasons not to)
Why would there need to be a right to abortion?
Because it was needed **to protect women** To enable them to choose something much safer than pregnancy/childbirth...there would be no need to protect women's right to bodily autonomy, medical privacy (health decisions), and due process if some states were not denying women those protections recognized under federal law (the Const). The RvW decision clarified women are entitled to those protections. States may not supersede that.
RvW decided that the states may not deny women a safe medical procedure if they choose it. It is much much safer than pregnancy/childbirth
Why should women not be allowed the safer medical procedure if they choose it? The unborn have no legal standing to affect that. The govt is obligated to protect women, and to protect our Const rights.
