This has nothing to do with "ecumenism". This and similar laws in India are simply denials of human rights and freedom of religion by Hindu and Buddhist religious chauvinists. So long as there is no coercion, no one can or should be prevented from choosing to following the truth that is the Catholic faith. No Catholic, including the Pope and the bishops of South Asia, would agree to or suport this kind of law. Thus it has nothing to do whatsoever with "ecumenism".
I think the implication may have been that there are no "sweet fruits of false ecumenism".
The pope and bishops continue to compromise the Catholic faith and "stress the things we share with people of other faith traditions", as well as hand our churches over for pagans to worship demons, etc, and stories like this one show exactly how far all of this nonsense has gotten these people.
Are they now, after 40 years of this madness, convinced of their need to convert to Catholicism? I think not, and such reports highlight the fact that the world is becoming more convinced in its error rather than the opposite.
