This is all really a level of logic we shouldn't have to descend to on Free Republic. The state already has oversight of women's bodies while they have occupants. Already has. With your support. Are you unaware that it is illegal to pull your unborn child's head ("the occupant") out of the uterus and suck out the brain? If this is illegal at any point then, again, we are not arguing about the line. We are arguing about where to draw it.
Point taken. So, using my example above, what, if anything, would you do if you saw an apparently pregnant woman in a restaurant, having a glass of wine or smoking?
