As a physician from a European country, where circumcision is not routinely performed on babies, I can.state that the research in that documentary was correct and the arguments were valid (ok, that guy with the frenulum orgasm was ridiculous).
For no male in Western societies exists a necessity for a preventive circumcision. Yes, uncircumcised boys may have small infections from time to time on their foreskin, but those are mild and harmless. Phimosis is also quite common and often treatable with steroid ointment - harmless.
Penile cancer, another argument for circumcision is nowadays completely preventable with the HPV vaccination, also recommended for boys. Also, if this argument would be valid, let's do a preventive.cervix conization for all girls to prevent cervical cancer.
The transmission of HIV being less with circumcision is crazy as a) you should use a condom to protect yourself against all other STDs anyway and b) for the majority of heterosexual men, HIV is relatively rare anyway.
Also, I cannot hear this hygiene argument anymore. This is completely idiotic. As you take a shower everyday, so does your glans - that's it. We could also start to remove women's inner labia for the same reason.
The advantages of keeping your foreskin on the other hand are numerous, when it comes to sexual function.
As for religion, I want to provoke a thought experiment: let's assume, I now found a religion where we sacrifice the 4th left toe of every child to God. Would you forbid this religion and this practice? Why? The 4th toe has less function than the foreskin! Only because my religion is 2,000-3,000 years younger than yours? Where is my religious freedom?
As you can see from my comments, the documentary is thought provoking in itself.
