Today, we have the Party to ensure Ingsoc is forever, and to purge oldthinkers from Oceania (formerly North and South America, England, Australia, and some places in Africa). Oldthinkers unbellyfeel (read: lack the full emotional understanding and blind acceptance of) Ingsoc.
No one is permitted to burn the Oceania flag, or show any dissent. Dissent is crimethink (thoughtcrime). Crimethinkers must be purged. Goodthink (Party orthodoxy) can only thrive when thought is controlled, and any action which defies this strict orthodoxy is a threat to the power of the Party, and thus to freedom (i.e. slavery).
If we were to allow the burning of the Oceanian flag, or dissent of any kind, it would allow people to question the authority of Big Brother (our glorious leader who lead the revolution). This authority must go unquestioned …
How can freedom exist if we allow people to do as they like? Simply stated, it can’t. All freedom, all peace, all justice, comes from the Party, under the guidance of Big Sister. For the sake of freedom, we must dictate what activities persons are permitted to do, and monitor their actions.
Oldthinkers believe in the slavery of the individual over one’s own self. They called this “freedom,” as though a single person can be free, without the guidance of Big Sister or the collective knowledge of the Party to show them what freedom is. Ingsoc advocates the freedom of the Party over the people in all fields of life. Victory can only be achieved through purging (murdering) oldthinkers, thus removing the crimethink before it spreads to others.
