There are 28 million Christians in India - India has had Christianity since 52 AD.
If you put "assimilate", then you put those 28 million Christians at risk.
I know, you're going to point out persecution of Christians in India - and it does happen, but not everywhere and not all the time. The south and west of India has had Christians for centuries and the north-east is a purely Baptist land (Nagaland, Mizoram etc.)
There are times you make sense. That's somewhat disconcerting.
