Well, my friend, who I was talking about on another thread (she has two circed boys, is pregnant with boy #3, and I've tried to talk her out of circing him) - she said that her doctor's practice went over both sides of the circumcision argument - pros and cons, and didn't push either side.
So I think she feels that she researched before making a decision.
But I don't think the pros and cons she heard ever included anything about the proper function of a man's foreskin, as everything I've told her about that seemed to be news to her.
So - did she research or not? I think she did, but she didnt' find all the facts before making their decision (her fault? or her doctor's fault?).
It's an interesting question, though. I can't quite imagine anyone reading all of the information in Fleiss' book and still choosing to circumcise.
