Speculation again
! Definitely you and I would not be there to examine their descendents (that is a certainity).
Btw, I dont believe that anybody here decries the impact of the immediate environment, societal forces etc., in the behaviour of an individual.
All agraharams, in the old, were in the middle with NB colonies around them. Even now brahmins live in a diversified environment; the next door neighbour may be a muslim, christian or a dalit. Brahmins dont seem to grudge this, and they continue to co-exist.
