Animal Farm Question About OrwellWatch
The pigs manipulating the more simple and uneducated animals is parallel to the Russian Revolution where Stalin and people like Molotov with him (the pigs) convinced the lower working class (the animals, who represent the proletariats) that they were helping them, when in fact they were in pursuit of power.
Imo, Orwell makes the other animals really stupid to create a clear juxtaposition between them andn the pigs, adding into the ultimate ending of the story.
They are also unquestioning and do not really challenge the pigs. Boxer's blind loyalty is not valued by the pigs or repaid and the ultimate tragedy (for me...poor Boxer) is what the pigs do to him at the end.
