"The ONLY reason this has become such a large issue is because the parents and husband disagreed in this matter."
Ya know, I personally think that the "husband's" appeal to "right to privacy" is the ONLY factor we need to consider in understanding how and why this case has become so difficult. Were we all on the same page with all the facts laid out squarely before us, it still boils down to the controversy of euthenasia... it appears you have asserted approval...
If you think that people who pull the tube and other life saving equipment from their loved ones in hospitals all over the country are engaging in something you don't think should happen, work with your legislators to change the laws.
And be sure to tell your loved ones that you wish to be kept alive through artificial means, even if you have no cognitive ability, for an indefinite period of time. Make sure your wishes are well known, preferably in writing, and the hospital and ultimate nursing home will be happy to keep collecting money and keep you alive.
