Shift of responsibility? I blame individuals for their fat, I blame environmental factors, like companies and city structures, when society is fat. The logic of your argument is that individuals cause obesity, but if that were the case we would see obesity rates stagnate within societies despite societal change. This is simply inaccurate to our present day predicament. I mean no disrespect, but you can't look at micro factors when you want to address macro problems, just like when an individual blames society for their fat, you can't look at macro factors when you want to address micro problems.
