JAY MANNERHEIM, psychologist: ''Gloria Wealdon has simply touched off unpleasantries that in many cases would have exploded sooner or later anyway.'' MILO WEALDON: ''I never realized my wife had such contempt, such loathing for me until I read her book.'' MIN STEWART: ''My family has been here for generations. I consider Gloria Wealdon so vulgar as to be quite beneath contempt.'' GLORIA WEALDON: ''The hell with everybody in this snotty town. They made my life miserable. Now we're even.''
