I don't understand it in any context. You can't have "sort of" absolute rights. Either a thing is or it isn't.
If a fetus has absolute rights to life, then it bulldozes the mother's rights, if it doesn't, than the mother's rights are on the table, and lacking devine intervention, her rights are obviously quite a bit stronger than a fetus's rights. It is devine intervention, or sentimental intervention that supports the argument otherwise, no matter how well wrapped up in spurious claims of logic parsing.
