Opinions are personal, and facts are impersonal. If a fact could be personal, it could not be written down. If a fact is dependent on personal experience, writing itself is a waste of time. If not, we conclude that opinions are more important than facts. Statements of fact seldom come without opinion; this might be why we can't help sharing news.

Calling something a scientific fact suggests that you are not willing to argue it; and such a thing is, in fact, a belief.
