Who has the authority to identify which facts are not somebody's own? Can a fact be converted to an opinion by prefacing it with "I believe..."? Is an opinion forbidden if, like your own opinion here, it's stated in the form of a fact? What happens to people who published facts that later turn out to be wrong? Are the retrospectively punished? Are the people who denied those "facts" before they were disproven somehow compensated for having had their rights wrongly restricted? I don't think you've thought your idea through at all and are just grasping at an excuse to make your political belief sound authoritative. Remember when people used to say America invaded Iraq so it could control the oil? That was counter to the official reason for the invasion so, according to your idea, they were not entitled to publish that. It was also not harmless self-expression because it could have altered public opinion about a war, which can have serious consequences.
