I get the impression from reading this thread that in general most people would agree (based on the assumed cultural bias for circumcised as the "norm" in this country) with the following here:
Most people here in the US circ out of ignorance, because they "didn't know any better", had mis-information about it from other people, their husbands insisted and they just go along thinking it's a minor snip-snip with baby not feeling any discomfort of pain.
I don't think someone would drop a friendship with someone they find out had in the past circumcised a child with no knowledge that they were inflicting permanent physical and psychological harm-- Not to mention, permanent physical damage forever depriving them of the most sensual and sensitive tissues on their body. Most people don't feel that way in this country because in some areas of the US it is so culturally ingrained that people just think "it's done" like cutting the cord after birth or getting shots.
HOWEVER, when you are friends with a woman. They know you for years, and you are open and share all of the information with them.
When they read it and literally admit to you that circumcision is again unnecessary, that they know their child will feel pain, that they know they are depriving their child of valuable sexual tissue...they admit to all of that...YET STILL do it...well, then I think most people here would have difficulty maintaining a friendship with someone who did not act to protect their child from harm and protect their right to an intact body. To knowingly let someone harm your child...when you could have stopped it. I think that IS the issue.
I know someone who did just that. We shared the information with her about circumcision. She read it all, watched the video. Agreed with us, said she didn't want to do it. She even told us..."I just handed them the baby and let them take him away so I could go out of the office so I didn't have a chance to hear the screams." When the mother let it happen, defying her natural instince to protect her child...mainly because of societal norms and going against the grain of her family...sigh. It's honestly hard NOT to let a situation like that affect your friendship, regardless of whether or not you try to get past it. She said that in her case, she figured even though she agreed with all of the sexual side effects and knew that she was depriving him, that she figured he would never know what he lost anyhow...just like her husband never knew what sensation he lost since he was circ'd...so what was the big deal...

: .
This particular person, who I went through that experience with....well, she sort of fell away from our group of friends. Everyone was so shocked when they found out that she voluntarily drove her son in to be circ'd (after she told all of us she agreed with us and *knew* it would cause him harm). I mean, literally...the girls in our group were so sad and nobody could think of her the same way ever again. Even now, years later...whenever I think of her that is what I think of.
