Mr. Obama was expected to visit the Golden Temple in Amritsar, India, next month, but there were questions about how he would cover his head. Sikh tradition requires that men tie a piece of cloth on their heads before entering the spiritual center. The president, who is Christian, has fought the perception that he is Muslim. Sikhs are regularly mistaken for Muslims. A Pew Research center survey in August found that nearly one in five Americans say Mr. Obama is a Muslim.
“We have worked so hard to establish in America that Sikhs have a very different identity than Muslims,” said H. S. Phoolka, a prominent Sikh lawyer in New Delhi. “It is very unfortunate that even the White House is conveying the message that there is no difference between Muslims and Sikhs.”
