Nanak preached quite radical ideas for those times.The idea women could be equal to men was virtually un thinkable in most parts of the world in almost every society. He spoke against the caste system, of priests, soldiers, merchants and untouchable. Just imagine being in the lowest. Where you could have no contact with any other groups ever. You could not touch or associate folks different then your caste and had to announce every time you entered a village by making noises.The lowest rung of society. Imagine being fated to that position for your whole life and your children and theirs, forever. Truly revolutionary ideas indeed.

Sikhs might have broken off with Hinduism. But we still see God in each and every person even if that person violates that view.

"Na Koi Hindu Na Musalmaan" were one of the first words of Guru Nanak Sahib after he is believed to have attained enlightenment in the Bein river. He stuck to this message of equality of human race irrespective of religion, caste or color of skin for rest of his life by rejecting philosophies of both religions and creating a new religious order in Sikhism. He preached equality of humans and stressed that loving devotion to God and singing his glory is the only way to salvation. He also asked his followers to work hard to earn a living and share with the less fortunate.
