voluntary – adjective

1. Worthy of being ignored.

USAGE: President Bush calls for voluntary reductions of greenhouse gases.

2. Compelled to choose because of one's contingent circumstances.

USAGE: But whether we are speaking of U.S. troops in Iraq, or Canadian troops in Afghanistan, it is important for the reader to remember that the overwhelming majority in our voluntary armed forces utterly despise the Barbara Boxers, Jack Laytons, and media flaks who shed crocodile tears for them, and exploit their anxious or grieving families. Our forces in the field are purpose-driven, and do impressive things every day; men and women alike, they face real risk with true manliness. They have a mission, to find and kill mortal enemies of all higher civilization, and it is the moral duty of every decent human being to wish them godspeed in that task.

COMMENT: Why do you need a mandate to deliver an outcome you're already going to get?
