I would put people who cirumcise healthy boys in the pro-circ camp. I would not classify people who circumcise boys for medical reasons** only as pro-circ.
Also I think its worth mentioning that I'm pretty sure that there are a lot of Jewish people who wouldn't circumcise their sons except that they feel obligated too. I realize that many people won't understand this, but my impression is that they really don't feel that they have a choice. And yes this falls under anecdotal ...
So what you are saying is that, with the exception of Z, we are all on the same side? Damn, we are a cantakerous bunch, then.
