"It shows beyond a shadow of a doubt that they are motivated by "what they want to write"."
Agreed. See my #14.
I guess I can only add that I have two friends/acquaintances that are/were fairly high up in the journalistic trade. One worked for a major metropolitan newspaper and one still works our govt funded news organization. They are both hard core lefties in their personal mails and when I express my countervailing opinion they think I'm a right wing kook. And these folks are the ones in charge of two of our major media outlets. I can only assume they are fairly typical of their brethren.
