Have you noticed? The conditioning is evident.

There is a segment in George Orwell's dystopian novel, 1984, where he wrote about the Two Minutes Hate:

In the dystopian novel Nineteen Eighty-Four (1949) by George Orwell, the Two Minutes Hate is the daily period during which members of the Outer and Inner Party of Oceania must watch a film depicting Emmanuel Goldstein, the principal enemy of the state and loudly voice their hatred for him followed by declaring their love for the Party leader Big Brother.

The political purpose of the Two Minutes Hate is to allow the citizens of Oceania to vent their personal hatred towards a political enemy. In redirecting the participants' emotions away from the Party's governance of Oceania, the Party minimizes thoughtcrime and critical thought while exerting ultimate control of the population.
