Despite India’s millennia-old history of nonreligious movements, most atheists and rationalists choose to keep quiet about their skepticism of faith — it’s easier and far less risky than going public in one of the world's most religious countries. The space that does exist for debating religious authority and belief is shrinking, said Avinash Patil, a religious skeptic who was born Hindu and is now a leader of an anti-superstition group working in one of the country’s western states. “When you are open about it and engage in activism, it can get challenging, and even dangerous,” said Patil, chairperson of Maharashtra Andhashradha Nirmulan Samiti.
