How many news articles have you read about Dalits ? And leave govt. sponsored, the upper classand even police is involved in this.
Do you know if they use same water source, their hands are cut off, if a Dalit do a crime, their women are gang raped, not just one woman, many, in open. They are paraded naked.
I know this thread is not about Dalit and its off topic but the persecution is similar as one class look down upon and disrespect the other.
And yeah Indian govt. has failed to stop this violence against Dalits just like Pakistan govt. failed to stop this violence against Shias.
