Say what? I'm 62 years old, Catholic all those years and been circumcised all those years (well almost all :). Catholic boys have been getting circumcised at least that long I would say.
Well, apparently in my family, they did NOT.
Possibly regional difference?
Also, there was a REAL PUSH in the 60's to circumsize little boys for "health reasons", and there was nothing religieous about it. Just something the doctors and hospitals pushed for.
