Because there are still people who insist on trotting out the "all news sources are equally bad and all trying to push an agenda" chestnut (no, they're not), a couple of offerings.
One, not for the first time, and probably not for the last:
Fox News is quite literally responsible for the legal precedent in the U.S. that the news media can lie to the public.
Two, more unscientifically, I took the liberty of jotting down the "metered" responses on the first 100 results on Politifact when searching for "Fox News", "CNN", and "MSNBC".
Fox News had about 44% of their metered results rated "mostly false" or worse; CNN and MSNBC each had about 29%. Fox News also had as many "Pants on Fire" results as CNN and MSNBC put together.
Other media sources, particularly in the 24-hour news cycle, certainly have their flaws and biases. They're sensationalist, afraid of getting scooped, slow to make corrections and retractions, and quick to jump on promising false leads.
Fox is worse. Far worse. Multiple studies have concluded that people who make Fox their only source of news are less informed than those who get news from other sources, and one infamously concluded that
they were less informed than those who claimed to watch no news at all.
So if you want to claim Fox is no worse than anyone else, you should back that up; from where I stand, that's dogma, not reality.
