People should understand that Guru Nanak Dev Ji also didn't agree with the caste system in Hinduism. There is a difference in Religion and Nationality, my friend. When I meant "Fasle Sikhs" i meant the fact that when people think that you or their children should marry in the same caste - your going against Guru Nanak Dev Ji's philosophy. Which is "everyone is the same - no matter the religion, race or caste".
