Freedom of Speech?

SEE HERE Is truth socially constructed? Some people think so. Certainly we often arrive at ideas through perceptions that are biased. Suppose people want you to think a certainly way, wouldn't they naturally try to control your point of view and only show you the side favorable to their particular cause? The truth can't be arrived at in an environment that prefilters the data. All the data has to be considered and evaluated and judged before a conclusion is rendered. This is interesting.
