"Such an argument can be made for the regulation almost any human behavior: diet, smoking, hobbies, sports, etc."
You are SO correct. Walter Williams speaks the truth. This is another incremental loss of our independence. Walter frequently writes about the tobacco nazis, who started out so innocently, and now want to ban smoking in your own house. Soon, it will be food. Bought time we had a new federal department to keep people from eating the wrong food, coming to your home refrigerator so we can keep insurance rates down, of course.
Feh, who needs laws in the first place, ANARCHY NOW!
