This American Life has an entire show dedicated to the story about how homosexuality was removed from the Diagnostic and Statistical Manual of Mental Disorders, or the DSM-IV. The hour-long show is fascinating, but I was struck in particular by how one of the most pivotal events in the story happened at a gay bar in Hawai"i.
Part of me would like to visualize Hula’s Bar and Lei Stand as the scene of that moment, but Hula’s has been around for 35 years, according to its web site. That would put it around 1975. The American Psychiatric Association revised the entry in 1973, then removed it entirely in 1987. Maybe it’s plausible?
