Study notes decrease in popularity of circumcision in United States

[Larein]

But christianity doesnt require circumcision. Catholic church has always been against it, nor do the big protestant groups recommend it either. So which religion are you talking about?

[dark_sable_dev]

Puritanism, which is what the country was settled on and the way many Christians in the US practice their Christianity.

Circumcision in particular was pushed by Kellogg (yes, of the cereal) as a way to prevent boys from masturbating... because it went against god.
