Why Is the Theatre in a Unique Position to Force

Why is the theatre in a unique position to force and focus public confrontation about social issues?

A) Playwrights' politics have usually been the main reason they write plays in the first place.
B) The theatre has traditionally served as the best medium to transmit a direct statement on an issue,thus convincing the audience of a specific point of view in an aggressive manner.
C) Most productions do not act as propaganda but present the issues in all their complexity as food for thought and as such focus public debate,stimulate dialogue,and turn public attention and compassion to important issues.
D) The theatre has never been historically connected with government institutions and therefore has nothing to do with social issues or government decisions.
