Sikhs are neither Muslims nor from the Middle East. Sikhism is a religion of India. The roots of Sikhism lie in Punjab (India). Sikhs make up 60% to 70% of the total population of Punjab, which is the only region in the world where Sikhs are in the majority.

Shortly after 9/11, a Sikh was attacked in San Diego because some idiot couldn’t tell the difference. It was sad and very unfortunate.
