I've had this happen with people trying to figure out wealth based on very specific questions regarding where my parents live, etc -- I run the other way. Better to know sooner than later right?
Two of my best friends are Indian Americans, and our friendships were natural and formed around shared experiences together, character, etc. It is nice to form friendships on a blank slate.
Sure do note, this is a friends' mom so atleast a couple of decades older than me.. I've a good friendship with her son, so i guess it's just a question of being polite with her and limiting spending time with her.
Similarly, other Catholics attempted to integrate the caste system into Christianity in India (see the Malabar rites controversy), and had two different "castes" of priests, one acting as Brahmin's and ministering to higher castes, and one acting as Hindu priests from lower castes (pandarams), ministering to everyone else.
What's worse is the discrimination they face sees almost no recognition, since on paper neither of those religions acknowledge caste.

There are indeed situations where in parts of the country there are even cemeteries divided on the basis of caste but this is far from being the norm.
However, there are many low caste priests and even bishops in Christianity - which is a very rare occurrance among Hindus where priests are almost exclusively brahmin except for very rare exceptions.
