1) Many people choose to believe what feels right to them, rather than dispassionately seeing things for what they are. Unfortunately there are a great many of people that do this regularly, and they have practiced this their entire lives. Richard Feynman cautioned us in saying that "The first principle is that you must not fool yourself - and you are the easiest person to fool." That caution was aimed at scientists who are already among the most objective of us, yet they can still suffer from this ailment.
2) When people talk about the facts, they rarely just lay out the facts dispassionately and without judgement. Humans need a motivation to tell a story, and most people's motivations include convincing other people to support their ideology, or else berating those who dont. Facts are organized within a mental framework of the ideology of the teller, wrapped up in beliefs, desires, and biases andcarry additional information about which ideological position you ought to hold -- sometimes they are even intended to mislead and manipulate the listener.
The modern news media is composed of businesses in search of profits. That goal is often not aligned with a straight reporting of facts. By pandering to an audiences ideology they increase ratings. By reporting on salacious and exciting news, even if incorrect, they get ratings. Buyer beware.
