A baby in the womb is dependent on her mother for her existence during the first nine months of life. But this dependency doesn’t mean she isn’t a person, or that she has no rights.
Every single person that has ever lived needed the environment of a womb to grow in. There, a baby draws nourishment from the mother, yet her body remains a separate entity with its own blood supply and unique genetic make-up.
The vulnerability of the baby in the womb shouldn’t be taken as a reason to deny her basic human rights. Infants outside the womb show the very same dependency on their mother, albeit in a different form.
