For #2 if we say "Then it would be incorrect to think that X is morally wrong" is there an "X" that is always true in all places and for all times? I ask because "boiling a human child alive for pleasure" seems to be safely chosen to be something that everyone in all places ought to be able to agree is wrong but there have been other chosen Xs at other times in our own culture that have changed and are now no longer considered "morally wrong". This would seem to indicate that the X is subjective. How subjective is it? What is it a function of?
