If you are clear with the partition of India, Pakistan divided itself from India to be a primarily Muslim country. India on the other hand, chose to be secular. India is home to all major religions in the world.

And now we are taking a step backwards by creating this divide. Many of these people speak the same language, have the same culture and have lived their whole life in India, and the government just decides to stripe them from their citizenship, because they belong to a specific religion?

How is this in any manner ethical?
