William H. Gass said this quote
“ If someone asks me, “Why do you write?” I can reply by pointing out that it is a very dumb question. Nevertheless, there is an answer. I write because I hate. A lot. Hard. And if someone asks me the inevitable next dumb question, “Why do you write the way you do?” I must answer that I wish to make my hatred acceptable because my hatred is much of me, if not the best part. Writing is a way of making the writer acceptable to the world—every cheap, dumb, nasty thought, every despicable desire, every noble sentiment, every expensive taste. ”
