That is not true. Pundits and PR
people are mouthpieces for their agencies. Journalists are ethically bound to be impartial as much as possible. I think you might be giving her a pass because we are used to blogs and web content being confused with actual journalism.
Also, while journalists are given assignments by their assignment editors, real journalists would not allow their editor to tell them what questions to ask or how to spin a story.
Maybe the word moron is inappropriate, but I stand by the sentiment. I have had countless religion classes, having attended Catholic school from first grade through college. Non-Christian religion classes are routinely taught by Christians and non-Christians are routinely hired as professors in Christian colleges. It's ridiculous (and moronic) to assume that only Christians can research and talk about Christianity and Jesus.
