Recently, on three different occasions I had the opportunity to share a table with an Israeli and an Indian each time. Six different individuals, and I had the opportunity to watch their attitudes as they discussed friends, family, country, work, vacations, etc.
The difference in cultural attitude was strikingly stark -- Jews have a strongly ingrained value that "you shall not play down your race", the Indians were more than glad to bad mouth their homeland. As an example: The Jews speak their mothertongue at home and bring up their children strongly in the Jewish tradition, but the Indians seem to prefer to speak English at home, rather than their mother-tongue. Small data set to generalize from but: Wow!
Does this not say something about survival of the race vs individual?
