Sikhs are nice by the way. I don't like the thing about not cutting hair or not drinking alcohol, but I like a lot of the other tenents of their religion. I like how they discourage any type of superstition or ritualistic behaviors like pilgrimages or fasting, discourage any type of celebate and reclusive living and insist on all humans being equal to the point they don't even have priests or any sort of clergy. And of course their emphasis on how wealth and material possessions mean little. It's actually a very leftist religion. Probably my favorite after Christianity, and certainly better than the Robertson/Falwell branches of Christianity.
Yes, but they are very unsanitary with that hair. The smell is not pleasant.
