So you think that it would be best for the government of India to legislate people's conscience? You obviously have no concept of freedom. Why do you even bother to take part in a forum named "Free Republic"? When it comes to the concept of freedom you are clueless.
You must be living in a fool's pardise if you think conversion (especially the Christian kind) is all about people's conscience and freedom of choice.
Missionary business in India is mostly a big time scam. Even the government knows that....... and so the laws.
