Perhaps 1984 itself is amusingly the best example to explain this argument. The main character's travails and the lessons therein are too anthropomorphic, but the initial insight Orwell had that would lead to the book's premise is much more interesting: the idea that nuclear weapons would either favor large authoritarian states or small groups depending on their ease of production.[0]
Maybe anthropomorphically is the wrong word to use here, and I should simply have said thinking of systems vs. thinking of stories. You can see the difference by reading Orwell's theoretical vs. more human scale essays and books, but it's his human scale that is almost exclusively remembered by most people in his case. Although I love that book, Homage to Catalonia is no less a children's story than Animal Farm.

You seem to be basing your view on a single book. Is there anthropomorphism in 1984? Homage to Catalonia? Consider also reading some of his essays, as well as his books.
Orwell isn't all about pigs and horses. Animal Farm was a children's book.
