I know in the Holocaust, some German soldiers would differentiate Jews from Christians by ordering men/boys to pull their pants down and if it was a circumcised, they assumed they were Jews and took them away...now it is a universal practice for most Christians (In USA at least) to be circumcised. When did this happen?
I would certainly be interested in understanding how this became so prevalent in the USA; the practice is somewhat unusual in most other parts of the West.
