I noticed Muslims are in conflict with Buddhists, Hindus, and Sikhs, even more so than Christians and Jews. They know that first hand in India and South Asia.
The Sikh religion itself was born out of the Hindu-Islam rift in India, where the martial sects of Hinduism separated to convert the nascent pre-Sikh cult formed by Nanak into a completely martial faith bitterly opposed to Islam.
This religion, and the Hindu/Secular Marathas caused the Mughal Empire to weaken substantially. Coupled with the British arrival into India, this was the final end to Mughal/Islamic rule in India.
The Sikhs formed a large portion of British-Indian Armies during WW-2, and continues into the present Indian Army.
