The conservatives (rightists) think that their civilization is not being given the respect and praise that it deserves. They want to see only the bright side of their civilization. They prefer to ignore the areas of darkness. The liberals (leftists) think that their civilization is being given too much respect and praise. They prefer to ignore the bright side of their civilization. They want to see only the areas of darkness.
Both sides are wrong in this debate. A study of both—the bright and the dark side is important to have a fair picture of the past.
Both sides are violent, inept, corrupt, and decadent. The conservatives destroy lives outside their country; the liberals destroy lives inside their country. The conservatives blame their woes on the outsiders (everyone who is not an original member of their culture or ethnic group is a barbarian and an invader); the liberals blame their woes on the insiders (everyone who is not a leftist or liberal is a counterrevolutionary, racist, and bourgeoise).
They are the two faces of the Ancient Roman mythological entity Janus. One side of the Janus face speaks falsehoods towards the right (calls itself conservative or rightist); the other side of the Janus face speaks falsehoods towards the left (calls itself liberal or leftist).
