Assholes exist. Surprise! That's nothing to do with the actions of the parents.
The things they have done which are positive far outweigh that bullshit.
But people here are more keen to hunt for the negatives and enjoy an argument, no matter how inappropriate.
What have they done?
Seriously. they raised a ton of money on the back of peoples ignorance to pay for a treatment that didn't exist, that will now go to charity.
They prolonged the suffering of a human being for no reason, they repeatedly attacked the hospital and implied that the staff were mistreating him and effectively killing their son, they released countless posed pictures of their poor child in staged positions that made him look far healthier than he was (he cannot breathe unaided, cannot even control his eyelids, yet look at the pictures they release where he appears like a normal kid).
The parents are directly to blame for this press fiasco, and the world wide attention to the case. They sought out the press and every crackpot they could find to push their case.
Ask yourself this - this is not the first time this has happened. Hospitals have to make painful decisions on behalf of grieving parents numbers times a year, particularly something like GOSH. Why don't you ever hear about those cases?
