Just remember that people needing transplants need to get the organs from somewhere.... I prefer not to be that donor though.
I have been explaining the concept of freedom of choice to our 8 year old. One example is that of helmets. Should we force everyone to wear them or let them make the choice and live with the consequences. If we force others to do something like wear a helmet, can we complain when they try to force us to do something we would rather not do?
For adults, I lean towards letting them make their own choices no matter how stupid or wrong I think they might be. However, for kids, some things to need to be regulated to protect them from their parents stupid decisions...
In my state, thankfully the laws jive with my views... those under 18 are required to wear a helmet, but those over are free to be organ donors.
Sorry for the tirade...just don't get me started on healthcare, smoking or the second amendment...
