You cannot print a story if you have little space in which to print it, time to write it, or the money to hire a professional to do so. Many editors insist resources are too thin to support religion coverage. But anyone who understands newsrooms knows budgets are windows into the priorities of those who manage them. Budgets help shape news. You cannot write a story if you do not know that it exists.
Journalists work hard to become trained political, arts or sports reporters.
But editors do not consider it a high priority to hire professional religion writers. It's hard to write a story if you don't care that it exists. The result is, at best, a blind spot on religious issues and the people who care about them. I believe this is the most powerful bias that shapes coverage of religion news. It's hard to produce balanced, fair coverage of people you dislike, distrust or whom you feel are irrelevant.
