There is no power in protest.  This is a direct result of its overuse as a tactic by the left of center in Western democracies since 1968.  Martin Luther King led the last legitimate protest movement in America. It is worth going over the footage to see his protesters decorum and focus with the anarchic and vulgar protest of today. This is without even going into the substance of the issues. Voting rights versus ... a wage roll back for teachers?, not getting government cash for your disease?, anger at losing a Presidential election? 
The comparisons are pathetic and the conclusion is evident - protest as a means of power in a democracy has de-legitimized itself into irrelevance.
It's just a parade with bad slogans and sometimes a giant puppet show. Democracy requires more.
