this is not caste system. caste system is not part of hindusim but part of hindus. other religious people doesn't need to come to temple as they can't pray to krishna and they can't chant aum. similarly when we go to churches we can't pray jesus. we just respect them. if allow non-hindus in temple it will be like we allowed mugals with our in fights from afghan to kerala. see the state now. so please read history rather blaming caste or rituals. but vayalar if he is not christian beliver what tantri did is wrong any sense. Punyahm is not needed for krishna but we should not allow other religious people coming to temple otherwise tommorrow you will repent. if you sit in aplace where you are supposed then good otherwise dog sits there . that is what is happened to so called global hindus
