  The proverbs "the enemy of my enemy is my friend" and alike capture the
essence of many body correlations in social relations, whose violation leads to
social tension. We study how rule-breakers, who disrespect these norms, affect
the structure and dynamics of signed social networks which tries to minimize
social tension. We find two dynamic phases. A friendly society exhibits a
"united phase" where insertion of a rule-breaker only leads to localized
rearrangement. A hostile society exhibits a "divided phase", where insertion
leads to macroscopic reorganization of social relations. In the divided phase,
starting from the utopia state, where all relations are friendly, insertion of
a {\em separatist}, a particular type of rule-breaker who makes friends with
only half of its neighbors, leads to fragmentation, where the society breaks
into many finite size, mutually antagonistic cliques. These phenomena are
described by Ising lattice gauge theory, where social tension behave as $Z_2$
topological defects, which are confined in the united phase and deconfined in
the divided phase. We further show that the connection between social dynamics
and Ising lattice gauge theory is viable independently of connectivity
structure of the social network.
