What about the secular jews or jews converts to christians?
Anyway this is common in every cultures from anglo saxons to
japanese, that's why people formed their own clubs and
associations.Every groups wanted advantages from their own
networks
Yes, the unintended side effect is it creates groups that can
become quite hostile to outsiders. It fosters xenophobia if left
unchecked.
There really isn't any solution as long as the goodwill can be
converted into tangible form and then transfered. It may turn out
that money is the root of all evil after all and not the love of
money.
