Look, there is no caste system in Christianity, but I said many times here that Christianity and Islam in India adapted a lot of culture from the sub continent.. That is why when people say we are destroying India culture, I oppose it.. Because I personally saw many Hindu culture has been adapted by my religion.. Any way thats not the topic here.. You have to understand that people converting into Christianity does not make them rich or make socially acceptable to every one.. Also understand that not all the Christianity belong to SC\ST or Backward caste.. I do have to admit that, Christianity in India also have caste system to an extend.. I also have witnessed it personally many times..
I have to agree with you here, i only posted about caste system in other religions in india as its a norm for Monotheistic religions to denigrate hinduism in the name of its caste system and its beliefs and calling themselves as descendants of arabs or middle east and that they have nothing to do with this land and refuse to associate themselves.
