Fox were dead, news of his death would have been broadcast worldwide, meaning that you would have heard or known of his death in some manner. Perhaps people think that Michael J. Fox is dead, due to the fact that he does not seem to be in the public eye, or in the press very much these days, because of his ongoing battle with parkinson's disease, which caused him to retire from ABC comedy series Spin City several years ago.
