The guy takes some rare incident in Wisconsin (a state - as many states in the U.S. - probably the size of some European countries) and makes it out to be some how normative in both the state and country. No it is not. There are people that believe all sorts of sh*t in the United States (the NOI thinks space ships are hoovering above to take black people away and destroy white people). It would be better to find statistics on how many parents in Wisconsin take their children to the doctor or hospital when they're ill or infected with disease.
I knew a Jehova Witness (I think that was his religion) who stated he would not get blood transfusions because its against his religion. Granted, there are a number of JW's in the U.S., but he's the only person I ever met in my life that expressed something like that. Most people I know in the U.S. not only visit hospitals or clinics, but over medicate themselves, AND their children. The contemporary answer to any hyper-active boy, or depressed child in the U.S., is to medicate them. The business is so large American commercials are filled with drug advertisements. Hell, they make living with Herpes look like fun on the American drug commercials. And you know how many people in the U.S. live with diabetes and take insulin?

Plenty. I have one nephew, one uncle, and a friend that has diabetes, and that friends mother died from diabetes. The United States in terms of population is the third largest in the world. Three hundred million people live in the U.S. With a population that large it should not be strange to find people doing things outside of the norm.
Believe me, there are plenty of criticism to be launched on American culture (obesity and disposable culture for example), but people not going to the doctor is not one of them. I know someone who allows exploratory surgery on his back (nothing wrong with him) just so he can collect disability ($$). And actually, bacterial diseases in the U.S. are mutating so rapidly now, largely due to a combination of Americans being prescribed drugs for every little thing, and Americans not finishing their drug prescription completely, but rather ending the medication when their symptoms leave (the bacteria then are not wiped out, but some survive, build up tolerance, and mutate).
