I'll take showers and condoms, thank you very much.
I'll also take a vaccine over surgical intervention.
Also, it's kind of weird to take results from a third world country and apply them to developed countries.
Muslim countries probably do have lower HIV rates, but congratulating circumcision for that fact is fraught with confounding variables. Most of Europe has negligible circumcision rates with lower HIV infection rates than the US. Over course, people use condoms much more often there. (Thanks Religious Right of America!)
People who trumpet these studies always confuse me. You do know that there is research that shows that female genital cutting has analogous benefits to circumcision, right? You might as well ask the ladies: "Time to take a bit off the top of your labia. Why not?"
