You are erroneously attempting to compare pregnancy to something else other than pregnancy. You see, this is an impossibility because there is nothing else like pregnancy in the known universe. You cannot equate what we are and are not allowed to do on the outside of the womb to what we should and should not be allowed to do inside the womb. When you find a situation where one human being lives completely and totally within another human being outside of pregnancy, then you’ll be able to compare apples to apples. Until then, you are simply comparing an orange to an apple and arriving at illogical conclusions. We did not violate our mother’s body while we were gestating, we were sharing a single body with another human being as intended by evolution. The very purpose of a woman’s reproductive system and the organs that support it is to generate, nourish, and protect new human life, not destroy it.
Where do the rights of the woman over the fetus’ body come from if “nobody gets rights over the body of another, ever”? Gestating fetus usually does not pose a threat to the woman’s life (and when it does, measures must be taken to deal with the situation – sometimes this sadly means that the baby is lost), but abortion always poses a threat to the fetus, killing it with near 100 % certitude.
