Italy's highest court ruled that Italian men can no longer grab their genitals in public. The defendant in question, according to the New York Times, argued that he was innocently adjusting his overalls. Regardless of the reason, discomfort or display, the court put an end to an age-old Italian tradition of warding off bad luck by touching one's genitals.
The court ruled that the practice was contrary to "socio-ethical behavioral rules requiring everyone to abstain from conduct potentially offensive to collectively held feelings of decorum.”
Since offensiveness is inherently objective, do you think it's possible to outlaw bad manners? Are there collective feelings of decorum?
