Right, we moved on from the general case of autonomy to the specific case of right to life (killing). As you point out as far as bodily autonomy goes since a fetus is entombed in the womb I would tend to agree, the main significant issue of bodily autonomy really is just reduced to, does a fetus have a right to life or not.
So I am perfectly happy talking about "do we have a right to kill this entity" as a more simplified point for debate that is also entirely equivalent to the original point.
That said I am still very much at a loss as to what your position is from my last question where I was trying to understand it (but the response didnt help me).
