Is Nudity a Persuasive Method of Activism?

A naked person might make you either look twice or cover your eyes; but activists in Spain hope it will persuade you to join their cause against bull fighting. Over the weekend, anti-bull fighting demonstrators in Madrid dressed themselves up in not much more than fake blood. They were trying to raise awareness about the animal cruelty involved with bullfighting.

Going naked or using sexy women to bring attention to neglected causes isn't new. PETA (People for the Ethical Treatment of Animals) routinely uses human flesh to get out its animal rights message; they even orchestrated a Running of the Nudes to protest the infamous running of the bulls in Spain.

Do you think nudity gets people to pay attention to important causes, or does it come off as a distracting gimmick?
