I was a drama major in college. Of course we all had to study the "great playwrights"; and many of our acting and directing scenes were culled from plays by Miller, O'Neill, Tennessee Williams, Shaw, et al. Looking back, almost all the plays were nothing more than screeds against the American Dream; or were pro-homosexual and pro-communist, etc.
Speaking of staging scenes in drama class, I once played one of the cops picking up the young immigrant protagonist in that play.
