FOX is not a news organization, it is a punditry organization. Their goal isn't to provide unbiased information and allow the viewer to draw their own conclusions. Their purpose is to sell their own narrative, and they push that narrative relentlessly, day in and day out, regardless of what's actually happening in the world. If something doesn't fit their narrative they misrepresent it or ignore it.
For example, there's currently a big kerfuffle about a production of Shakespeare's play Julius Caesar, which casts a Trump look-alike as Caesar. The FOX depiction of the event is "TAX FUNDED PLAY 'ASSASSINATES' PRESIDENT" and "If this was President Obama and they behaved in this fashion, you cannot even imagine the international outrage."
In actuality, the exact same theater group put on the exact same play in 2012 and their Caesar was a Barack Obama look-alike. Nobody freaked out, none of the sponsors walked, and FOX had no problem whatsoever with the production. But 5 years later they left all of that information out of their "reporting" because it didn't fit their narrative.
There are endless examples of this phenomenon. Here's a
link to the FOX News page on Politifact. Some here will tell you that the folks at Politifact are just a bunch of liberal liars, but they explain all of their conclusions in detail so you can judge for yourself.
Long story short, if you think that conservatives are the best kind of people, never make mistakes, and deserve to be in charge, and liberals are greedy, stupid, incompetent morons who base all of their decisions on doing the most possible harm to honest, God-fearing Americans then you'll love FOX. They'll reinforce all of those ideas and give you someone else to blame for all of the world's problems. On the other hand, if you value objectivity, context, and honesty and you like to come up with your own conclusions based on good data you'll want a different news outlet.
