How does the drama in "The Crucible" represent the concept of belonging?

In the end, the idea of belonging lies at the very essence
of the play.  The drama unfolds in the strict definitions of "us" and "them"
oppositions.  There is a sense that those who are not part of the accepted social
community are "outsiders" or "witches" and need to be punished.  This manipulation of
social perception of belonging helps to detract attention from real and substantive
issues and offers an easy target to rally public support.  Miller shows how peer
pressure as well as individuals seeking to belong can do some fairly horrific things
because the fear of being "alone" is a difficult reality to embrace.  The need to belong
drives people in Salem to ends that actually end up severing bonds with one another.  It
is this idea of belonging that lies at the very center of the drama in
Salem.
