you know how backward classes were treated by hindus in ancient days ....your forefathers might be untouchable as per hindu religion ...they might have been canned by brahmins while entering a temple ....your grand mother might have been forced to be a devadasi ....just imagine how they might have survived so that they could see the next generation which can atleast bring revolution and abandon the cult which divides human in castes and catagories ...
there was no culture before invasion of india ...people use to live an animal life......so dont talk about culture and all that stuff...
