[naasking]

> 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.

There were other times when thunder was thought to be caused by Thor. What bearing does that have on the fact that thunder is actually caused by lightning which is generated from electrostatic buildup? It doesn't mean that natural facts are subjective does it?

Moral beliefs are not moral facts, just like beliefs about natural phenomena are not natural facts.
