Decry illegal immigration all you will, and I add my voice to that, but please don't confuse it with Sikhism, which is one of the world's better and more enlightened religions
Sikhism preaches that true path to achieving salvation and merging with God does not require renunciation of the world or celibacy, but living the life of a householder, EARNING AN HONEST LIVING, and avoiding worldly temptations and sins.
Sikhism condemns blind rituals such as fasting, visiting places of pilgrimage, superstitions, worship of the dead, idol worship etc.
it also preaches that people of different races, religions, or sex are all equal in the eyes of God. It teaches the full equality of men and women. Women can participate in any religious function or perform any Sikh ceremony or lead the congregation in prayer.
They fought bravely with us in WWII, and during the last London riots, while shops were burning and people fled, no damage was done to any Sikh owned shops, why? because the owners brought out chairs and sat in the entrances wielding their swords, - the mob made a sharp exit.
