For me, "freedom of non-expression" is perhaps equally if not more important than freedom of expression.  It needs to be OK to not say things.  It needs to be OK to not do things.  You should never feel pressured to do things "because you should".  That doesn't mean you should always run away from everything and fail to face what actually needs to be confronted.  But paradoxically, it is hard for me to take an action unless I first know that not taking an action is also OK.
