What does it mean for a moral statement to be true?
It's hard to give a general answer to this, as different moral realists would answer this question differently. Most would agree that it means that there are facts about one ought to do and not do.
How do you tell if something is a fact?
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
