If so, how?
I often hear "direct action" used to describe activities that seem purely reactionary or symbolic from my perspective.  For example, when do you believe that the smashing of a window qualifies as direct action?  When do you think it qualifies as expression?  Both?  Do you differentiate between the two, perhaps contextually?
I will refrain from immediately posting my own opinion, but I will take a moment to express that I brought the window-smashing up arbitrarily.  I could have instead used picketing, gardening, dumpster-diving, voting, lock-ins/occupations, etc.  I will post a link to a related question as a comment below.
