Conformity is vital. Dissonant feelings and voices are evil and must be suppressed or effectively countered. We value faith and obedience. Doubt opens the door to confusion and the slippery slope of amorality and immorality. With the threat of non-belonging as a carrot and the right to belong as a stick, morality keeps people in line.
Choices are either moral or immoral.
Complexity tests our moral fortitude. We follow the single legitimate source of moral guidance and authority. All modes of morality are reducible to the application of moral principles. We know our moral truth to be factual and universal. If other's don't realize this, they should.
