Some form of public repression of facts or speculation not desirable to some people or even a majority of the population seems inevitable as societies need to create some common basis of facts to create a unified identity. Critical to political and personal freedom is the level to which this repression is organized through the state or powerful private organizations. Western secular societies have reached the consensus through the late 19th and early 20th centuries that private organizations should not be allowed to engage in compulsory censorship, forcing people to obey their dictates. For example, the separation of church and state in most Western societies mostly prevents religious organizations from repressing individuals based on their personal opinions and beliefs. As well, people are generally allowed to leave employment with a company which may regulate such personal expressions for whatever reason and find employment in less restrictive circumstances.
