you are all way off base here. Circumcision doesn't reduce AIDS risk. People who have their kids circumcized are more relgious than people who don't. In this case, they tend to be more conservative muslims.
Study shoud read: People with basic concept of morality less likely to contract AIDS.
I know of many wild people who have been circumsized and are not at all religious. (NYC)
Such as Jewish friends who are atheist/ nonreligious but raised with Jewish traditions (hence they were circumsized)
