They're simply holding off until they get their UN lapel pins around the time they change their name to WBC (the WORLD Broadcasting Company).
===================
The Washington Post today noted that ABC journalists are barred from wearing lapel flags. "Especially in a time of national crisis, the most patriotic thing journalists can do is to remain as objective as possible," says spokesman Jeffrey Schneider. "That does not mean journalists are not patriots. All of us are at a time like this. But we cannot signal how we feel about a cause, even a justified and just cause, through some sort of outward symbol."
Why are you changing positions at this date? And when did you begin favoring objectivity in the news? I have never had any trouble detecting your network journalists' negative signals about their views and feelings about the Republican party, and in particular, President Bush.
Perhaps your sponsors need to know that you HAVE been disclosing your biases, over and over again, you suddenly decided to stop short of showing patriotism. One wonders just why patriotism and loyalty to our country is a bad thing at ABC....
