What does Sikhism say about prejudice and discrimination?

Sikhism teaches that people of every race are the same and should be treated equally:

From one clay has the Creator made countless shapes, sizes and colours. Neither are the vessels badly made or does the Creator lack any skill.Guru Granth Sahib, pages 1349-1350

Sikh teaching on the equality of women

Women were another group who experienced prejudice and discrimination. They were prevented from entering places of worship while they had their period and in most cases not allowed to visit at all. They did not have a separate identity, as they belonged to their fathers, husbands and later, sons.

The Gurus taught instead that women and men were equal. They appointed women to lead prayers and had men cooking in the langar. Women who joined the Khalsa were expected to bear arms and had their own surname for life: Kaur meaning princess.

Purdah was rejected, as was the full-face veil. This cannot be worn in a gurdwara.

Guru Nanak wrote a famous hymn in praise of women and closed it asking:

Why curse Woman, from whom all the greatest of men have been born? None can exist without a woman.Guru Granth Sahib, page 473
