I never said that they shouldn't cover this. In fact, it's maybe reasonable that people with agendas do investigative journalism that only covers the malfeasance of one side and faction. I'm not really sure. I certainly wouldn't discourage any outfit to do credible reporting on any story just because it might help or harm another side or just because they might or might not have biases. But that being said, I do think it's worth pointing out that the outfit does have a bias. What's the harm of letting people know?
