What is the purpose of Two Minutes Hate?Thanks in advance =]

Two minutes hate is a way for the government to exert more
control over its citizens.  Essentially, it is a way for Big Brother to ensure that the
public focus is on those deemed dangerous.  The idea of being able to generate images of
revolutionaries like Goldstein on a screen for two minutes and connect an image to the
public in order to ensure that the public's understanding of enemies are the same as the
government's.  Two minutes hate helps to consolidate their own control of the public
trust and also ensures that the public's understanding mirrors their own.  In this
light, it goes very far to helping to eliminate the realm of the private, making the
setting all public.  In being able to identify who the enemy of the nation is in the Two
Minutes Hate, Big Brother develops another way of maintaining its hold in how the public
thinks and who is seen as "enemy of the state."
