As we've seen again with the Weigel/WaPo nonsense, many reporters have a conceit that because they pretend to be superhuman truthtellers unswayed by the petty concerns of mere mortals, that they actually are that. They begin to believe their impossible claim of having no opinions, and start confusing their opinions with facts.
Of course Weigel didn't lose his job because he had opinions, he lost his job because he had the wrong ones. Also bloggers suck.
