The purpose of the news is not to express an opinion about something that is happening in society. Objective means the same thing but it does not mean you have to express an opinion. For instance, in the paper there are two sides to a story and they are both right. So, whether you agree with them or not is immaterial because the point is you read the news.
Objective news is simply the reporting of the facts as they happened. It does not involve your opinion on anything at all. If the reporter adds anything to the story it goes against objectivity. Opinion. News is just the straight up reporting of an event as it happened.
Some people believe that only newspapers publish news because there are so many topics to cover that everybody has a chance to voice an opinion. This is true to an extent but there is so much more to the news that it must be well presented. You cannot take the opinion of the newspaper editor into account when you are reading the news. It is not fair to do this. The end result is that you get a well-rounded and accurate version of what is going on in society.
