These people brought delicious chocolate and candy to the masses at affordable prices.....and levels of Obesity and Diabetes have never been higher. They made/make money from the misery of others, you don't want any part of that. Hershey is no different from the Tobacco companies.
I would tend to disagree. Obesity is a factor of many things, lack of exercise (Americans drive everywhere they no longer walk - cars), American children no longer have PE (electronic toy have taken over for athletics and play), Fast food is the norm, soda is the norm, etc. To say it is all caused by eating choc is very short sighted.
