This is sadly true, Nancy.
American playwrites from that time were fascinated by women´s sexuality and insanity versus love, which was a preromantic notion in literature like "Tristan and Isolde". You can see that clearly in Tennessee Williams´"Suddenly Last Summer" . The character played by Elizabeth Taylor is insane and her insanity was brought on by rape as well. The doctor gives her a "truthdrug" and she tells all about her cousin´s homosexuality and debauchery that killed him in the end. Note the marvellous character played by Katherine Hepburn, God rest her soul. What an actress!
In Streetcar, Blanche Dubois is desire/insanity/death reincarnated. She is thrown away by Marlon (What a man glorious looking man though!!!Stella!!!LOL) but she gets up and goes on seducing "strangers", as she is escorted out by the psychiatrist. Good for her. Another film that explores Streetcar is "All about my mother" by Pedro AlmodovÃ*r. Lord, I cried when I saw that film...
