Quote from : The Seven Basic Plots: Why We Tell Stories Book

The kind of self-righteous intolerance once associated with the more puritanical forms of religion and the more extreme forms of Socialism now reappeared to promote the 'rights' of women, homosexuals, racial minorities, the disabled and any group of people who could be portrayed as being 'below the line' and therefore discriminated against...Unconsciously they were using the belief that they were acting in the name of selfless moral principle simply as a cloak for asserting their ego, and as a means to enjoy feelings of moral superiority. In the cause of 'toleration' and promoting collective 'rights,' they had become possessed by a fanatical and humorless intolerance.
