Some hindus say sikhs came out of hinduism to feel superior, they say they are tree religion and other are branches but they are wrong because dharm is not in dna. We don't care if our ancestors were hindus neither Gurus cared. Everything having an origin and being older does not mean you are better than someone or you are right, Guru Nanak said exactly this that pandits and qazis are trying to take ownership of truth. Hindus don't have any legal claim over civilization of subcontinent. Sikhs, jains & buddhists have equal right over it. According to this logic humans came out of africa so we should go back and follow their native religion.
