Sikh's have a concept of equality:

"According to Sikhism, men and women are two sides of the same coin of the human race, a system of inter-relation and inter-dependence in which man takes birth from a woman, and woman is born of a man. Also, according to Sikhism a man can never feel secure and complete during his life without a woman, and a man's success depends upon the love and support of the woman who shares her life with him, and vice-versa. The founder of Sikhism, Sri Guru Nanak Dev Ji, reportedly said in 1499 that "[it] is a woman who keeps the race going" and that we should not "consider woman cursed and condemned, [when] from woman are born leaders and rulers.""
