As someone with a disability, I find Micheal J. Fox's behavior to be personally offensive.
I would prefer to remain in a wheelchair rather than walk at the expense of my belief that embryonic stem cell research is the unnecessary destruction of life.
He is, IMHO, either a fool being used as a tool or a willing accomplice to an outright deception.
Rest assured if Michael thought his neighbors adult stem cells would cure him, he'd favor forced flensing and decanting of whoever could be caught.
