Well, some turned out to play with bands like Straight Ahead, Kronos Quartet, and The Klezmer Conservatory Band. A few believe that there isn't any sexism, either in the musical realm or elsewhere. Sure it's difficult to compose as a woman, but that's the state of the art for all composers, especially if they're experimental. There comes a point where women need to be less focused on themselves as victims and more responsible for themselves as artists. Musicians compose and play because they have to are born to not because they are encouraged.
Female musicians have no reason to be angry.
The whole point of freeform is to take a pluralistic approach to music. Each and every perspective is valid instead of the narrow mind of one. The problem comes when we do not actively question why or how our aesthetics are formed. We need to examine our own reactionary response. Unfortunately, it's only on college and community radio like WCBN that women are able to play music, recite poetry, discuss their concerns openly, and yes, even yell, if they want, about backlashes, inequalities, lesbianism, abortion, menopause, masturbation and music.
