what a load of crap, Guru Nanak Dev ji conceptualised Sikhism so as to reform hinduism, he was tired of all the evils in hinduism ranging from sati, to child marraiges, dowry, 10000 Bhagwans, casteism, cow molestations and such
so in order to get rid of these evils , he formed sikhism and the Khalsa, thanks to sikhs participation in army that india is safe or else india would have been burned to the ground long ago.
I think even if each hindu girl should lays with sikh bhaijis, tis not enough
