In India, where superstitions run rampant and accusations of witchcraft can be a deathwish for women like it was Salem in the 1600s, Birubala Rabha is fighting to protect them.
Journalist Vikram Singh documented her work for the New York Times:

Rabha has been successful in getting Assam State legislators to pass a law criminalizing accusations of witchcraft (the penalty could be life imprisonment if the victim commits suicide as a result). But that doesn’t mean the belief is gone.
Superstitions and bad ideas don’t disappear just because there’s a law against them. If anything, people who think sorcery is real may just think they’re being persecuted.
Still, the video offers a fascinating glimpse at how one person is trying to overcome irrationality.
