Why does Americans say uncircumsized is dirty

I see it this way, people are not very smart as a whole.....a person might be smart.......but people in general can be convinced that the moon is made of cheese if you tell them enough times. Taking that into consideration, it's not too hard to understand how people can be convinced that being uncircumcised is something so dreadful, hideous and potentially life-threatening. You see, for the most part, Circumcision is a practice that has been accepted as the norm in the United States.......same as for the Jews and the Muslims. Personally, I don't think there is anything wrong either way....whether you are circumcised or uncircumcised; as long as you are healthy, clean and know how to use it well. Unfortunately, there are those who will go to great lengths to try to convince you that being one way or the other is the better of the two......because of their own preferences. We all have a right to have preferences in life, it's what "The Pusuit of Happiness" meant when it was written into the Constitution of the United States. Unfortunately, the ignorance that exists in many parts of the U.S. is staggering....in many different levels; be it religion, politics, and even education. People learn more from little news flashes they see on TV, than from doing their own research on a particular subject.....take, for example, the FOX News channel, with it's flashy news flashes. People hear in the News Flash that a study has discovered that uncircumcised penises have a tendency of exploding during intercourse.......HUH? Oh my GOD, I must remember never to go near an uncircumcised penis!!! DO you understand what I am trying to convey here? If people as a whole would really try to understand the information that is being given to them, they wouldn't be so caught up in ignorance.
