For westerners, some of the important values of Sikhs they can appreciate.
1) Monotheistic. One God only.
2) Opposed to discrimination due to religion, race, gender, or social status.
3) Are more realistic, less idealistic. They believe in both good thoughts and good deeds.
4) Strong believers in secular military service, and loyalty to the army in which they serve. (The Indian Sikh regiment is one of the most decorated regiments in the world, including 14 Victoria Crosses as part of the British Army. Sikhs fought in WWI, WWII, and other conflicts.)
5) Typically Sikhs are middle class and are attracted to entrepreneurial and professional lines of work.
6) Both Muslims and Hindus have tried to oppress them in past, and they do fight back if attacked.
7) Were banned from US military service in the 1980s, and the Army still strongly resists their return, but two Sikhs have been permitted to serve and deploy, a doctor and a dentist.
Sikh gangs are heavily involved in the west coast drug business.
Sikh businesses in Canada require knowledge of punjabi, so of course employees have to be flown in from punjab.
The first ever act of terrorism in Canada was committed by a sikh.
