I do not find it funny, personally speaking. 

No one is forcing people to buy products. But if government forces stopping it, that is called a Nanny State and quite frankly, they need to myob, unless it is criminal things that impact others who are not involved around them. Besides things like meth labs, people on welfare should have that money stopped if they test positive for illicit drugs, after all, innocent people, taxpayers, are paying them so we are involved. If a child is obese, and taxpayers pay for their foods, that needs to be stopped-the tax support, including health care-UNLESS that child is on steroids for a major health issue, causing this weight gain.   

*Like that.
