Answer:
Even though the portrayal of homosexual topics, homosexual characters, and events, have appeared in literature since ancient Greece and Rome, it took a really long time for audiences to either accept, or even embrace, even the mention of such a topic as homosexuality, of any kind. However, with the evolution of social paradigms, and the more active roles played, especially in the arts, by homosexuals, this reluctance began to disappear. But it was not until the 20th century, that almost total oppenness came regarding this issue, and America was not the exception. The authors in America, who throughout the 20th and 21st centuries, were known for being some of the first to openly, and clearly, discuss and present themes and topics of homosexuality, particularly male homosexuality, were: James Baldwin, Allen Ginsberg, Gore Vidal, Tennessee Williams and Truman Capote, between the 1950´s and 1960´s.
