> breadth of viewpoints gives richer coverage
Breadth of viewpoint has nothing intrinsically to do with the color of one's skin.
> Journalism, good reporting, brings deep informed insights from the ground. That's not going to happen when reporting on foreign countries and disadvantaged communities if all the reporters are (say) from a WASP background and perspective.
Again, the quality of a reporter and their work has nothing to do intrinsically with the color of their skin.
