He's correct and circumcision is ubiquitous only in the USA - Why? Because after WW2, understandably, a large contingent of Jewish immigrants into the US and by the 1970/80's nearly all OB/GYNs were Jewish Doctors - therefore, circumcision became a common practice. In fact, if you grew up as a boy in the 1980s/90s in the US and we're NOT circumcised - you were ridiculed in the locker room for having and "ant eater" 🤣
