Comment: While I Don't Reject That there are Regimes Whose Rule at Times Have Been Undemocratic and Oppressive to the Official Opposition, I am Of The View That Equally The Official Opposition Sometimes is at Blame at What Happened To Them. 
Democracy is All About Good Governance and Availing Opposing Views To Be Heard BUT In Accordance With The Prevailing Laws. 
It's Not Secret That Some Opposition Parties Have in The Name of Democracy Used Subversive Ways to Challenge The Government of The Day, Using INCITATION, HATE SPEECH, DIVISIVE RHETORIC and Some Even Planning SOCIAL UNREST ( With or Without) The Aid of Foreign Elements YES!
In This Situation You Won't Expect The Government of The Day to Stay Idle. 
Much as Those in Power are Expected to Uphold Democracy , The Opposition are in The Same Vein Expected to Uphold Democratic Virtues, Its a Two Way Process.  
The Opposition Should Let the Elected Governments Rule AND Should CHALLENGE Them Through PARLIAMENT and Other Established Avenues.
