But as a person who believes life begins at conception or at least within a trimester, I am completely opposed to anyone who states you have the right to do anything that infringes on someone's right to live. This is the epitome of a libertarian position.
Like I said, it depends on when you think living starts. Obviously it's not right when the baby comes out; that's a completely arbitrary barrier. Is it feasibility? I don't buy that either because a baby isn't feasibly when it's born... If it's not subject to constant care and protection even after birth, it will die. Plus, even before feasibility a baby has scientifically proveable cognitive functioning, a nervous system, reaction to stimuli and definitely can feel pain.
To me, those factors basically equate to life to me. A woman's right to not be burdened by basically a parasite does not outweigh the right of a living human to continue living; that's the essence of libertarianism.
Once you you agree that the baby is a living human, it's no longer a question of what the licensed Doctor says... It has rights!
