What inspired Alice Walker's stories?
Alice Walker's stories, by which I mean both her shorter (e.g. poems and short stories) and longer works, seem to me to be inspired strongly by her own experiences and by her social and political commitments. She is more like the returning daughter (the politicized artist) in the short story "Everyday Use," for example, than she is like the one who stayed home. Her novel Possessing the Secret of Joy and her film Warrior Marks similarly grow out of her campaign against female circumcision (which she and some others call "female genital mutilation").
As an aside, I agree with Walker (from what little I know) that female circumcision can be brutal and that the world would be a better place without it, but I have reservations against her wholesale denunciation of the practice and her campaign to bring it to a screeching halt. I don't like eveything about other cultures (whether outside or within the US), but that doesn't mean that I am the one to decide what other groups can and cannot do. I'm off topic here, of course!
