Why is it difficult for the pigs to convince the animals of the principles if Animal ism?

The pigs struggle to convince the other animals of the principles of Animalism because they employ manipulation and Propaganda, often distorting the truth to serve their own interests. Additionally, the other animals, being less educated and easily swayed, find it challenging to critically assess the pigs' claims. The pigs also exploit the animals' fears and desires for a better life, leading to confusion and blind loyalty rather than genuine understanding of the ideology. This results in a growing divide between the ruling pigs and the rest of the farm, undermining the original ideals of Animalism.
