If you were one of the “other people” would you want them to kill off a twelve year old so you could have some parts? Even if they were life saving parts?
When my friends donated their son's, he was kept on machines until there was ZERO brain activity...3 or 4 days. They can't turn a machine off and start harvesting parts.
The parents of the child I'm familiar with who had double lung transplant, pray for the parents of the "angel" donor everyday...always mindful that they lost a child
Your argument is ignorant.
