Well, speaking as someone who serves in a media relations role professionally -- and in a much higher intensity environment than a baseball team, too, I can say that this is generally not a good thing to do. However, sometimes you have to do it. On occasion, I've gone toe to toe with reporters and editors when I've felt they missed a quote, misunderstood a key point, mischaracterized a situation, or whatever. Frankly, I can recall several serious screaming matches with reporters and editors, and, while it was the right thing to do, it still left a bad taste in my mouth. As Bruce noted, such an occurence with him is usually related to an individual column/article. Same for me. I do not let it get personal, and I am very careful to keep it on the article at hand and NOT to make generalizations. But it's hard on both sides nonethless. And if you aren't very careful, it can have an enduring negative influence on your relationship with them. I don't know the particulars, and I don't know the personalities, so I don't think its fair to criticize in this case.
