Used as a derogatory phrase to criticise someone who unknowingly has slave morality. Most commonly seen with middle and upper middle class college educated Western Liberals (Both Conservatives & Progressives). The moral faggot satisfies status needs by signalling to the blasphemer that they are lower on their imagined social hierarchy by using GSRM (Gossip, Shaming, Ridicule and Moralising).

Also linked to Freud's "reaction formation" survival mechanism theory.
