Not sure if it is the result of propaganda, peer pressure or the general collapse in the standard of personal autonomy in our country but it seems 86% of the country support being told how to feed their children. That being said I wonder what the question was

B: Do you think that children should be able to run across busy streets, unsupervised, in order to stuff their craws with sweets, chips and other high sugar, fat and salt products that will no doubt reduce their lifespan by a factor of ten?
