Community Moral Origins.

beliefnet
In the cultural and moral history of humanity multiple communities are an almost insignificant part of our heritage.  Certainly not enough to affect the basic moral conditioning we recieve. So for practical purposes the face group of your parents is your community.  It is rare even today for mama's face group to extend beyond the parish, village, etc.  Even dad's community was generally local, the store the smithy, the farm.  So culturally one can be confident that the basic community values are those of mama. 

Multiple communities really began in the 19th Century when the schoolmarm with an out of town education came to influence the children.  Cohesive community morality began the slippery slope to competing community moralities.  We are still just beginning to learn how to deal with them.  Some still don't.
