The circumcision of male children is a central feature of both Judaism and Islam. It is also important in many African and New World cultures.
"Most people aren't aware that Islam, not just Judaism, requires male circumcision."
That's because both of them have Abraham, who God told to get circumcised, in their lineage. Which is true BTW.
Circumcision made sense if you lived in a dry desert environment with no dependable water source to clean oneself...other than for primitive reasons...nope seems archaic now.
