If a parent beats their child, the state can step in and remove the child from the harmful situation.
But if a parent allows their child to become overweight to the point that their health is affected, should the state have the same right to intervene?
In a commentary posted in the Journal of the American Medical Association, professor Lindsey Murtagh and Dr. David S. Ludwig, of Harvard University, argue that severely obese children should be removed from their homes. They also say that government involvement may be justifiable because of the imminent health risks, and the parents' chronic failure to address medical problems.

Some people have no understanding of the concepts of limited government and personal freedom.
If the government can take away your kids for being fat, they can take them away for any reason, social, religious or political.
