Then it comes down to whether or not being a journalist is a profession,
What makes something a profession? Having the college degrees? Passing an exam? Or just saying "I'm a professional," and a group of people agree?
If a profession is defined by the degree or an exam, then Hannity is not a professional, because he didn't graduate from a college and hasn't passed an exam. What he has been able to do is convince others that he has something to say, and can attract an audience with what he says. If that's a profession, then OK. But it's not a journalist, because he doesn't "journal," he speaks. One can say he writes books, but that makes him an author, not a journalist. There are many intermediate levels in writing, and not all writing is journalism. But what is a diploma, other than a piece of paper that tells others that a particular university accepts the credentials of this person as what he says he is?
We live today in a country where 16% of the population believes the President of the United States was born in Africa, and is therefore unqualified to be elected. To them, regardless of the facts, he will never be President, and he doesn't get the respect that comes with that office. That kind of thinking has been applied to lots of other fields, where people can convince others they're knowledgeable about a subject, and are therefore authorities on it because what they say jives with what a group of people believe. One can say that's how Christianity began.
So what does all this mean? That there is no such thing as the truth other than what we believe? Maybe. But at the heart of the issue, no one, whether it's Sean Hannity, Barack Obama, or Jesus Christ, is who they say they are...unless we're willing to believe. If we're not, no college degrees, professional experience, or even electoral results will convince us otherwise. We will ONLY believe what we want to believe. Is that really the kind of world we live in now?
