I have to agree on this one.
The rape argument is simply to get the camels nose in the tent.
Sometimes life at conception is an uncomfortable thing to defend, but it is not complex.
No, it is much worse than that, because a side effect would be an increase in spurious rape allegations, with near certainty. It is already apparent that many - if not the majority of - rape allegations are merely buyers' remorse. Adding even more incentive does not help things.
