A type of brainwashing invented by the government of the United States and crammed down your throat by schools since preschool. Translated into simpler terms, the pledge means this:
"I promise my complete loyalty to the flag of the United States, and to the government of the United States, which is a country in which everybody believes in and is ruled by 'God' and human rights are honored, with freedom and due process of law for everybody."
Although it promises human rights, there is no evidence of this elsewhere in the country, and half of the people who recite it every day probably do not know what it means. They just say it because they were told to, like good little subordinates.
Yolanda: "Have you recited the pledge of allegiance today?"
Richard: "No. I do not believe in such foolish brainwashing."
Yolanda: "This is not brainwashing"
Richard: "Uh oh, they have already infected you. Now you must be destroyed."
