Why is he somehow more "important" than all the other people on the bone marrow transplant list?

Does it matter? His situation is bringing attention to this, and getting more people to add themselves to the registry. Whether or not he is personally saved, it's likely that several other matches will be made as a result, so I'd say it's a good thing overall.

By my understanding, this isn't a matter of supply and demand, or him trying to "jump the line" by making a direct appeal to people - it's a matter of sheer volume, it's relatively difficult to find donors for anyone that match well, so having more people in the system is a good thing for everyone.
