This doesn't sound right. How do you "mislead" people into becoming Christians? And if that is possible, it is also possible that the Hindu right-wing is misleading these tribals into believing they were misled.....

Sounds to me like BJP pressure.

"How do you "mislead" people into becoming Christians?"

You tell them they're gonna burn in Hell if they don't (audio-visual aids showing flames and demons helpful at this point), and promise them that God will reward them with Western riches if they do (procede to distribute food and trinkets).
