We can pretty much agree on social issues at the Federal level: they are not Federal issues. The fight should only be at the local level.
The reason that social issues nevertheless arise at the Federal level is primarily the vast size and scope of the Federal government (including the court system). For example, abortion, gay marriage, etc., were purely State issue until Federal courts got involved.
The only areas which are legitimate points of disagreement concerns such things as the military and Civil Service system: these clearly are Federal, and there will be disagreement there–but these are small parts of the overall disputes.
