People always miss the point with this. Buddhism is essentially atheistic. People are choosing “no god” other a pantheon of gods who mandate that they be treated like garbage. It doesn’t improve their condition, however, It would be better if they became Christians. They will still face oppression but a whole new world of education, upward mobility, fellowship, and possibility open up for them!
Buddhist Dalits continue to have “reservations” as a scheduled class. The “reservations” are India’s version of “affirmative action”.
Christian Dalits do not. However, Indian Christianity is not “casteless”, and within Indian Christianity, the caste system still has a lot of power over who can associate with whom.
Buddhists do not believe in any kind of deity or god, although there are supernatural figures who can help or hinder people on the path towards enlightenment. While not believing in God, or a God, Buddhists believe in “the soul” (as in souls exists but there is no “creator”, just souls) and all souls keep reincarnating, based on Karma from past lives, unless and until they become so “enlightened” they reach “nirvana” and quit reincarnating for good. Then the soul will become another one of the “enlightened ones” and may assist lessor souls on their path of “enlightenment”. But no God.
