What values does Clarisse represent? Why must she be killed or silenced?

The previous post was quite strong.  I would probably
expand a bit on the second question.  From the social order's point of view, I think
that Clarisse represents a major threat.  Examine what she represents and I think that
she comes into direct opposition with the prevailing political order and its
expectations on the citizens.  On one hand, Clarisse reveals that she likes to talk and
likes to spend time with her family.  This is something that cannot be controlled by the
external government because it is something that transpires in the private and is
unpredictable.  It's fair to assume that Clarisse's conversations with her family, and
with anyone for that matter, are wide ranging and initiate more thought.  The fact that
this cannot be contained would cause an instant threat to the Status Quo.  Look at her
opening question to Montag of "Are you happy?"  The reader can make the clear connection
that this question really starts him on his journey of doubt and alienation, another
example of Clarisse's "threatening" nature.  Finally, I would say that Clarisse is a
threat because she is self actualized.  She does not care if people perceive her as
"different" because she revels in such a distinction.  In the end, these individuals
pose the greatest of threat to an establishment that wishes to present totality, a sense
of control, and complete guarantee.  She lies outside that which is quantified and
because of this, she would be seen as a threat to be
neutralized.
