I've stayed out of this fray until now, but I just have to address the "best person for the job" comments.
I'm in MBA school, and one of the things we study in Organizational Behavior, obviously, is diversity. I think that most people, and I probably did to some degree before recently, believe that diversity is some sort of rule to be complied with, and that you do so at the risk of losing quality among your employees. But what has been proven time and time again by scientific research is that diversity has an inherent value for an organization. It allows a company or work group or newspaper to solve problems better and in more innovative ways. It fosters creativity. It leads to greater job satisfaction for everybody. This is science talking, not liberal feel-good doctrine.
So it follows that sometimes the "best person for the job" can't simply be chosen based on a narrow set of qualifications for the particular job in question. Sometimes you have to take into account the big picture, or the long view, and have faith in your managers to get their employees to crank out good work. Yes, this does mean taking into account race, gender, sexual orientation, age, religion, you name it.
The problem that arises is that organizations have to value diversity, not just in their words, but in their deeds. These values have to come from the top, and people have to buy into them and believe in them at every level. Clearly some of the posters on these "minority reporters" threads do not value diversity, which is unfortunate. If everybody did, we would all be better off.
