Can you provide links or sources? Something? Googling "missionary abuse" brings up alot of hits...Most of which are porn. :-)
lol , frankly i dont know any source on the internet since a lot of government of india documents are not on the internet, but there are Indian government documents on paper and some done by the Tamil Nadu government. It was on basis of that report the Tamil Nadu government tried to bring a law curb the "mass conversions" phenomena.
I came across this when I was working with some NGOs during 99-01 when we decided we wouldnt cooperate with religious organizations after we found out about these abuses.
A lot of people who are living in India have faced this and seen this, even in metropolitan cities. In the cities usually shrug this off as the work of lunatics but things get a little bit more heated in the villages and hinterlands.
On the internet I found an article which is more of an opinion piece by Outlook

but this is not the documented evidence I am talking about ofcourse. It is just a persons opinion.
There is also the Supreme Court's 1977 verdict that the right to propagate one's religion (guaranteed by article 25 of our Constitution) does not include the right to forcible conversion. (Stanislaus v State of Madhya Pradesh, AIR 1977 SC 908) which the Vatican and other christian organizations strongly condemned.
Again let me distinguish between some missionary works who genuinly do work for the poor and try to convert by really helping the poor out, i really have no problems with them.
I have problems with those who actually end up using coercion and blackmail and other tactics and these arent the lunatic minority. They are a sizable chunk of the evangelist christians.
