LAHORE, Pakistan-As Pakistan, the sixth-largest nation in the world, struggles to implement democratic reforms, the country’s ban against kite flying is another intriguing battle between social moderates and religious conservatives over the place of Islam within society. On one side are those who contend kite flying has no link to Muslim customs, and therefore has no place in the Islamic republic, where 97 percent of the country’s 165 million people are Muslims. On the other are those clinging to the tradition of a popular sport. And caught in the middle are the people who make and fly kites.
