Becoming a spook, handing over lists of British marxists to the government, and writing anticommunist propaganda involving animals whose animated adaptation is funded by the CIA to own the Leninists
What I learned about this dude in school basically amounted to a hagiography
"One of the greatest writers of all time" my ass
It is however very easy to use animals to play on pre-conceived emotions audiences have with each segment of the "animal world".
Pigs being the political class. Horses being the industrial workers. Cows or sheep being the farmers. Whatever being the artists. And so on and so forth.
I dunno it's been decades since I read the book so I've probably gotten some bits wrong but you get the idea. You can easily prey on pre-conceived emotions people associate with each animal in order to give people underlying subconscious feelings about each group.
In reality the use of animals serves to make the book appeal to a younger audience and to manipulate the feelings of the audience from the very outset.
