I would hope most literate readers could tell the difference. There's an obvious distinction between a pundit advancing a point of view and factual accounting of some event. That's not the say that the news section never betrays bias with the facts a reporter chooses to include, or by omitting contrary perspectives. But really, I hope readers do not need a giant header banner "THIS IS AN OP-ED" to recognize one.
