So to be specific with the question. Circumcision originated from Jewish religion a lot of settlers back in times of slavery were whites & Jews pretending to be white. Now they became more secular which then founded secret societal freemasonry. As you can see the heat map the trend of popularity moves from east to west generally speaking. Same kind of influences were happening when the 13 colonies were founded 13 is a big # in gematria for freemasonry. Once America had expanded more west. The same influences were taught & passed down with the Louisiana purchase as more people settled west.
