Moral Conflicts.

Beliefnet
There are always two communities involved in any moral decision.  One is the "face group community:" my tribe, my church, my village, my SSG.  The other is the larger society one may consider oneself to be a part of: my city, my state, my religion, my nation, my fellow humans. 
I find it is almost impossible to violate face group moral standards.  If my church says God Hates Fags, I will drive to military funerals and try to protest with my handmade sign.  If my village says dark skinned people in hoodies are unwelcome it is moral to shoot them. 

It is when face group morality conflicts with the larger society that moral decisions may take us away from personal survival or community survival.   In both of the cases cited above the larger community may take issue with the local morality and prosecute the shooter, or prevent the protest.  Even to the extent of destroying the face group community or forcing the face group to adopt the morality of the larger society. 

The major moral issues that can shread a community occur when the larger community, the religion, or the nation, tries to impose its moral standards on other religions, or nations. Usually it takes a God to create "the other" that is not considered "one of us" and therefore undeserving of moral consideration, but there have been exceptions.  These lead to the ultimate moral violation where both individual and community welfare are violated: war between the larger societies.  Face group morality is irrelevant. Choose to go to war or the Gulag.
