which elements of propaganda are most prevalent in animal farm? why does orwell choose to highlight those forms of propaganda?

The pigs seem to be changing the rules to suit themselves and have ways of frightening those who speak out. The one pig who really had a good heart is ousted by the bad pigs....Something that “Animal Farm” and todays society have in common is that the powerless people are subject to propaganda . In “ Animal Farm” Squealer and Napolean used propaganda by telling the animals that Snowball was a traitor, and convincing them that he was a criminal. They threatened that if Napolean was not in leadership Jones may come back. This happens in our society during the election period , the opposing parties all warn the public of the consequences of voting the other party, and how bad it would be if they were in power.
