Can someone explain sikhism to me?

Also, in one of my classes, the prof said that Sikhism, particularly in New Jersey, was a touchy subject and that he did not want to get into it. Does anyone know what he was referring to?

People wear a turban and walk around with a big knife.
Nothing more.

Too complex to explain here

Sikhs are happy to tell you about it.but the faith prohibits going out and imposing it on others

Try wiped?DOA

Local/race faith. you hardly imagine non India is Sikh.

5 Ks one is the knife and one is a comb, hair is never cut.

a cross between Islam and Hinduism.

It is false that the children are taught to play hide and Sikh.

Dear ask er, New Jersey means the religious robe or dress which includes five symbolic signs namely Long Underwear specially designed in unique way(Kachhehara), Iron bangle in right arm (Karaa), one six inches symbolic sword fixed in, cotton cloth strip, worn from left shoulder hanging on other side (Kirpan), A wooden comb in hair on head for any time combing(Kanghaa) and turban (Keskee) on head (some religious scholars take the fifth symbol as Kesh i.e.hair on head). Please have a look.

When a follower of Sikhism is baptized he or she wears the religious robe as per the Sikh religious code of conduct.

But I don't think religious robe or dress has much to do with spiritual uplift except a separate identity and psychological awareness to the baptized Sikh for better performance of duties towards his or her religion. Otherwise he or she has to do as follows.
