What you fail to realize is that the very same people who are eager to classify some people as less than human are equally eager to classify other people as greater than human. You can be quite sure that Michael J. Fox would be in that latter group.
For instance, in the UK, certain life-saving treatments, like liver transplants, are reserved for people who are considered "National Treasures". Everybody else must go on a long waiting list, which is really a Wait-To-Die list. Ordinary people are just not important enough to merit the expenditure of government money, you see.
But celebrities, politicians and a few others are worth more than the rest of us ordinary humans. Michael J. Fox is surely one of these select few.
I don't believe it and neither (I think) does Michael J. Fox. The communists would throw each other in jail/execution whenever the party line changes. Michael J. Fox will be a forgotten memory within 2-3 years once he comes bed ridden and unable to talk (or defend himself). The Hollywood elite will forget him in a heart beat.
