The organisers of PETA's campaign against sheep mulesing should be congratulated for informing consumers about this dirty secret. The salutary lesson here for activists is that markets work: by presenting facts and arguments they can influence society and bring about change.
However, PETA should be worried about government interference. One element of its successful campaign is street theatre - an activity deemed so heinous that people have apparently been deported for it. And, as with mandating ethanol in fuel, the Coalition is prepared to undermine the marketplace to appease a very small group of farmers.
Despite the Coalition's wooly-thinking about liberty and economics, PETA understands that even national governments are powerless in the face of informed global markets.
