"It is my feeling that a story is not finished until it is read, and that the reader finishes it through his or her life experience, prejudices, world view and thoughts." -- Annie Proulx
Annie Proulx wrote Brokeback Mountain as an outsider, a heterosexual woman, looking on. I actually like the way that she did that.
Annie Proulx has admitted that she did not have all the answers to questions that she had about her subjects of Ennis Del Mar and Jack Twist.
But, as a person who has had two courses related to literary criticism (one secular and one religious), one needs to try to understand the life experience, prejudices, the world view and the thoughts of the author of the original work first of all.
But, I have found on the internet in various forum boards (not so much in this one) and in Yahoo discussion groups related to BbM that some women who are admittedly exclusively heterosexual in their sexual orientation think they know everything that there is to know about men who are exclusively homosexual in their sexual orientation. They even think they know gays better than gays know themselves.
