The problem with the rape exception is that you are still accepting the summary execution of a human life for reasons not germane to that life. There are of course better more humane solutions to the so called “rape” scenario, but they would never be considered in moral relativism of today.
I’mnot talking about accepting it, but the liberals use rape/incest (abortions forthese are just 1% of the total abortions) to justify the 99% of abortions that are for “don’t want the baby”
