The philosophy of some people called Duncan who believes in everything that is beautiful, wonderful, just, kind, total freedom for anyone who is cool, top quality, the best in the world (or at least close) etc. Duncanists hate and despise anything bad, low quality, ugly, and believe that assholes like that who believe in that shit should spend the rest of eternity in their self-inflicted hell. And we don't care (ref Sex Pistols/Malcolm Maclaren)
