Marriage is a prime example of a straight institution fraught with role playing. Traditional marriage is a rotten, oppressive institution. Those of us who have been in heterosexual marriages too often have blamed our gayness on the breakup on the marriage. NO. They broke up because marriage is a contract which smothers both people, denies needs, and places impossible demands on both people. And we had the strength, again, to refuse to capitulate to the roles which were demanded of us. Gay people must stop gauging their self respect by how well they mimic straight marriages. Gay marriages will have the same problems as straight ones except in burlesque.
— Carl Wittman, “A Gay Manifesto” (1970)
