Can everyone please shut up about Maria Callas?

One thing that exasperated me intensely during my many years as an opera critic was the assumption that I must be a passionate admirer of Maria Callas. She is the only prima donna who most people have heard of, and her supreme status has long been taken for granted, to the point at which the sound of her voice, as well as her personal story, have fomented a myth, a legend, an icon, and made any rational judgment almost impossible.
