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."
