I am sure there were some Muslims who converted . But alot of Hindus did voluntarily leave the faith for Sikhi back in the days of the Gurus . Brahmins dont have any hold now . Nopower is with them . They were evil , and are facing the karma of their actions . Even the priests nowdays are not all Brahmins . Nope . Not many Hindus . Just a small minority in the Northern India considers that . When I visit ChennaiTamil Nadu , many of the folks dont even know of the faith . They ' re always curious about the faith . Even the Iyenger Brahmins . This was a small propaganda by a Brahmin minority who did the same with Buddhism as well . Sadly , Buddhism died but Sikhi made it through . Hindu nationalists so called the RSS do Dharam Parivartan in Punjab by converting lower caste Christians and Muslims into Sikhi . You can google it . I do not support that , but its all vote politics . I dont see an active agenda to capture the Sikh identity by anyone , for now .
