I know that the belief in the majority is a core part of our democracy, but I'd like to challenge it for a moment here. First, does common belief make sonething right? Lets say society A has a majority vote that says people who murder are horrible and should be executed. Society B says no, murder is okay, because the majority say its okay. So, is murder right or wrong? The point is that a crowd doesn't always have a right answer. Second, opinions are not homogenous, and popular opinion can be wrong (think geocentric systems, newtonian laws, disease, etc.). A morality by plurality is arbitrary and non-universal which seems to defy the point of moral frameworks.
