Ray: We agree on this point - "Public ignorance perhaps needs to be addressed first before we can realize any progress." Education is the key to WHATEVER the answer is. Most people (again on both sides of the issue) ARE making their decisions without knowing what is really involved. The one point I think can't be overcome is the point about when life begins. I would stop fighting that point though, and put more emphasis on the point you have made about fertilization clinics and left over embryos which will be destroyed anyway. I DO find it ridiculous that no uproar is raised over the "leftover" embryos for purposes of procreation, which is (in my mind) not as serious an issue as the life and death issues of PWP, while at the same time there is an uproar over ESCR. I cannot think of a logical argument against getting some use out of embryos which will otherwise be destroyed for nothing. Logically, either both should be illegal, or both should be legal.

One guy suggested cryogenics. I can't seem to make the point that it is THIS LIFE THAT IS SO HARD TO LIVE and alone too. People seem to think you just get sick and die soon. They don't seem to understand that some diseases steal your life while you are alive and it is not all just old people. Perhaps this is the common ground we can find between supporters and non-supporters of ESCR. Unless you have an incurable disease, care for someone who does, it is almost impossible to understand. Guy who did my taxes thinks I need to relax more so I can talk and his wife has MS which is episodic. and she has had only one episode. Public ignorance perhaps needs to be addressed first before we can realize any progress. The only thing people seem to know is "that actor" MJFox It is very disheartening as I know people have been trying to raise public awareness for years. The well need to walk in our shoes.
