I wasn't trying to make a plea for community consensus. I think individuals come to their own conclusions about morality, but those conclusions are informed by the information that they receive from their environment and community. A person who never experiences meaningful debate, thought, or contemplation is going to be morally stunted compared to those who engage in regular debate and discussion. That doesn't mean every person who argues a point is morally superior, but in the aggregate, engaging in moral discussions will enhance an individuals expertise in determining moral veracity.
