NO. Just NO, I just dont believe in such a motion and would go against all my religiou beliefs.
I have just done an essay on this for my English discursive assignment lol.
A lot of people point out Spain as a shining example of the "opt out" option working wonders but what they don't say is that it's impossible to prove that it was the change to the law that caused the increase in donation rates. It was actually a decade after they changed the legislation to an opt out system before donation rates improved and that was AFTER they changed other things (e.g. employing more specialised staff and setting up a 24 hour donation task force) - even the guy in charge of Spain donation system says that he believes it was these changes and NOT changing to an opt out system that improved donation.
This is just one of the big points I would say.
If you have a look at any survey on organ donation, there is always a much higher rate of people for donation than are actually signed up to it. BUT in countried with opt out systems that still give relatives the final veto, the number of people who say they are for donation is also much higher than the percentage of relatives who agree to having their loved one offered as a donor. The reason for this is, it doesn't matter how much you try to rationalise it, it is an incredibly difficult decision to make - not least because the donor often has to be alive while the organs are harvested I believe (even if brain dead). The reality when you are faced with it is very different to facing it in the hospital.
I'm all for it, plenty of people don't care what happens to their organs once they die and don't bother registering to be an organ doner. As long as people are made aware of it and opting out is a fairly straightforward process I don't see why not.
Bar religion and the emotional distress for certain organs like someone feeling uncomfortable that someone would be using their eyes, I don't think there is really a good arguement..
"Oh sorry sir, the car crash has critically damaged some of your internal organs and we have several hundred matches from recently deceased persons....but no-one opted in for organ donation so...yeah...enjoy your last few painful hours."
