A "memory hole" is the deliberate changing of historical or other information that is not convenient for someone. The idea became popular by the George Orwell novel Nineteen Eighty-Four (1949) where the technique is used by the "Ministry of Truth". The idea was present in an earlier novel Animal Farm (1945).
A similar idea in the books is that of "doublethink". One often sees this idea in action in terms of "fact checking" whereby the "facts" checked may or may not exist in reality.

In computing this idea is sometimes called the "bit bucket" where "bits" of information disappear. Amazon does this by erasing purchased books from the Kindle when they decide the content is not suitable.

The web site called the "Memory Hole" attempts to preserve information that might otherwise be lost.

A secular story using pigs (or swine) as leaders of a well-meaning group taking those followers into bondage is that of the political satire book Animal Farm by George Orwell (1945). The "birds" appear to fit the role of the "pigs" in charge.
Based on the story of Soviet Socialism, the pigs, who took control after the revolution, are continually changing rules to benefit them at the expense of all the other animals.

All animals are equal, but some animals are more equal than others. George Orwell, Animal Farm.

Discussion question: How might the idea of casting pearls before swine be related to the pigs in Animal Farm?

The anti-religion, anti-Bible and anti-God writings of Karl Marx (1818-1883), the foundation of humanism, socialism and communism, emphasize the "community" or "society" over the "individual".

Pastors sometimes put these ideas into the church by carefully blurring the distinction between freedom in Christ and political and social freedom. Churches that promote socialism or humanism in this way tend to avoid certain parts of the Bible.
Only in community with others has each individual the means of cultivating his gifts in all directions; only in the community, therefore, is personal freedom possible. Karl Marx.

Society does not consist of individuals, but expresses the sum of interrelations, the relations within which these individuals stand. Karl Marx.
