1) It's not "India" that is doing it, it's a few Indians - private organizations.
2) As long as there is no coercion, it is legal and unproblematic. No matter which religion they convert from or to.
3) You can bet that the manner in which they may convert out of islam would be far more peaceful than the way their ancestors adopted it.
Note: I do not care about anybody else's religious beliefs, nor do I wish to convert anybody. I'm only recognizing the fact that people have every right to convert others through inducements (not coercion). After all, promises of a happy heaven after death is also a kind of spiritual bribery, and threats of hellfire and eternal torture for not joining one particular club is a form of spiritual threat. If people can convert on those promises, I don't see why they shouldn't convert for real money. And trust me, monetary inducement is used by every single religion - some more than others.
1) Pakistan has killed far more muslims than India ever has or ever will.
2) India has more muslims than all of Arabia, and by and large they live more freely than muslims in the birthplaces of islam.
3) Modi has not killed anybody, muslim or otherwise.
