> is there a movement towards broadening that definition to encompass any kind of sexual assault?
Yes, there's a dangerous trend towards redefining rape to include unwanted looks, bad vibes, sex while intoxicated, sex that you change your mind about after the fact, sex that was not good enough, etc.
"MS. SOMMERS: I interviewed a young women at the University of Pennsylvania who came in in a short skirt and she was in the Women's Center, and I think she thought I was one of the sisterhood.And she said, 'Oh, I just suffered a mini-rape.' And I said, 'What happened?' And she said, 'A boy walked by me and said, `Nice legs'.'You know? And that -- and this young woman considers this a form of rape!" - http://www.pbs.org/thinktank/transcript132.html
