Some good info on this site. I particularly liked this statement:
QUOTE
We believe that those who have served their country in the Armed Forces have earned the right to question, criticize, and dissent from the policies of the Bush Administration without being accused of “moral confusion,” “appeasing the enemy” or having their loyalty and patriotism questioned. We also believe that this right is the birthright of all Americans.
