There is a huge medical propaganda machine in the US. They talk out of both sides of their mouths.
The circumcised guys typically have a huge investment emotionally, like "it must not be useless, otherwise why would my parents have done it", not understanding all the effort the medical community has put into the fake studies, and the rationalizations to keep doing it, so they can continue to make money at it. The AMA and AAP say that it is not necessary medically, and that people should be educated, so they can make a good choice. Then, they make no effort whatsoever to either educate the people on the benefits of having a foreskin, or show them studies that both circumcised and uncircumcised men get the exact same diseases, at the exact same rates...or discourage the doctors from violating their Hippocratic Oath, "first, do no harm". They justify it with, well, it will bring the cancer rate down, and lessen their chance of getting HIV, of which neither is actually true. It's a 250+ million dollar a year industry, at least that is what the AMA was willing to admit a few years ago.
It sounds cynical, but I swear, it is true.
Why else would the US be the only country where a majority of the guys have had non-religious circumcisions?
Fortunately, whenever Europeans share their views, as you just did, it causes somebody in America to question this cycle. The rate is dropping very quickly, mostly because of the internet. Another reason is that many people have now played with an uncut cock, and realized they are not the hygiene horror show they were made out to be, they are actually fun.
