This retrospective meetup in the commercial O.K. Corral of American theater suggests that for at least some parts of the gay community, the canonization of milestone works is taking deeper root in the culture. Not that this signals any end to the struggles of gay, lesbian and transgender people, not by a long shot, or that the works of female and trans writers, particularly those of color, are as yet receiving the same level of prominent treatment as those of these white men. But, as Kushner noted in a telephone interview, the tide of history might be playing a part in this intersection of gay plays.
