text: Morality can't be decided by popular opinion, because right is right and wrong is wrong.\n\nJust as we can't decide the sun should move west to east -- we think whatever we think, but that doesn't change reality.\n\nHarm is wrong. 'Cause suffering sucks.\n\nWhat people DO decide, sometimes sorta by popular opinion, are laws, which are another matter (it would be nice if law and morality were better matched).\n\nAlso, changes in the arbitrary aspects of ettiquette are determined by popular opinion.\n\nUntil whoever it was in a previous answer said it was a shame that rape is considered wrong (if I'm understanding that comment), that person had a pretty good handle on it.\n\nBut clearly rape, as a particularly devastating form of violence, is clearly wrong.\n\nBut the basic idea that morality has to do with what we are, the kind of critter we are, is right.\n\nThe problem with the 10 commandment is that several of them are arbitrary and even silly (most of the people who go on and on about them violate them every Sabbath by watching sports, for example), and the list as a whole leaves out a lot of things that are wrong.\n\nFor example, it's wrong to put another person in a double-bind or lose-lose situation, where no matter what they do they are hammered or punished.
