Can you explore solutions to this problem. any ideas?
Social justice. Institutional reforms. Defense of human rights and human dignity. Giving dasvandh to those communities which really need it. When society addresses these kinds of internal problems, then you won't have mass uprisings of conversions among the Dalits and the tribals.
So there is already an overlooked factor here. The factor of deliberate mis-interpretation by foreign colonial powers to use religion as a weapon of cultural suppression and subjugation. And this is entirely independent from Christian religious teachings.
And my point was, in analyzing causes for mass conversions we have to look deeply at hatred instilled against the powers that be, which includes the central government of India as well as the authority of Hindu religion as being blamed by the disenfranchised, the discriminated, the neglected and the poor.
