@yetiwarrior outside of North America circumcision is mostly only the norm in majority muslim (or jewish) countries. https://en.wikipedia.org/wiki/Prevalence_of_circumcision (and as that notes Japan is close to 0%)
@Ibri I just surprised that circumcision is just common in only 1/3 of the world. Here in Indonesia circumcision is already common for kid until young teen. We only doing that once though hahaha. Some family even doing a banquet after their kids got circumcised. And there is common for mass circumcision in some rural community. Thanks for sharing the link. Sorry for wrong grammar.
