'Before India's independence , majority of hindus who converted were high caste. They did so to curry favor with the british rulers - for professional/material advancements'
Wow.. that is a huge generalisation. So you know personally many of those who converted and their reasons for doing so?
'Post -independence it was only the lower castes who converted - because of basic material rewards provided by the friendly missioanries - say a bag of rice. '
This is so ridiculous .. i dont know what to say to such rubbish.
'As I said , you only have half knowledge about India - there is a stricter 'caste system' among christians in India than aming hindus. '
Again thats a stretch, you dont see caste based violence among Indian Christians and casteism while it exists is not a part of the religion . However as you may like to deny it,Caste is a part and parcel of Indian hindu society and the role of upper caste hindus in perpetuating it and its history, no matter of revisionist history can change that.
'Hindus are not all bad and christians are not all good. Life is not so simple.'
I didn't say it is, it is you who is making broad generalisations and assumptions.
