alt Hacker NewsInter-communal trust sucks only when you consider well-being of a larger community which swallowed up smaller communities. You just created a larger community, which still has the same inter-communal trust issues with other large communities which were also created by similar swallowing up of other smaller communities. There is no single global community.
A larger community is still better than a smaller one, even if it's not as large as it can possibly be.
Do you prefer to be Japanese during the period of warring tribes or after unification? Do you prefer to be Irish during the Troubles or today? Do you prefer to be American during the Civil War or afterwards? It's pretty obvious when you think about historical case studies.
