text: should morality(right&wrong) be decided by popular opinion? who/what defines right and wrong? pop culture? god? religious writings? i have an opinion;  whats yours? morality can't be decided by popular opinion, because right is right and wrong is wrong.  just as we can't decide the sun should move west to east -- we think whatever we think, but that doesn't change reality.  harm is wrong. 'cause suffering sucks.  what 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).  also, changes in the arbitrary aspects of ettiquette are determined by popular opinion.  until 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.  but clearly rape, as a particularly devastating form of violence, is clearly wrong.  but the basic idea that morality has to do with what we are, the kind of critter we are, is right.  the 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.  for 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.
