I voted that I wouldn't cut them out, but would be upset. To be honest though, there likely would be some distancing (albeit subconscious) that came out of it. I know it's not about me, but it's natural for me to react to it. Think of it this way...if do something (become vegan, switch religions, change my politics, etc) it is natural that some of the people in my life will not fit with those beliefs, and they will naturally not want to spend as much time around me because we don't have those beliefs in common. Circumcision is much the same. It's something I feel very strongly about, so while I would never dream of purposely cutting somebody out of my life, that is a VERY big thing we no longer have in common and it's a natural reaction to withdraw a little when you see someone so blatantly display their radically different beliefs. For the record, when I speak about radically different beliefs, I am speaking more broadly than just circumcision...I just cannot stay close with someone who doesn't believe that autonomy is a person's right.
I also say this as someone whose brother and SIL will circumcise any future sons. It makes me sick, and I know that when they do have a son I will be really pissed off at them for hurting my nephew. However, they're family and will always be in my life to some extent. Thankfully my sister won't circumcise, because we're really close and it would devestate me for that to come between us. I told her what circumcision was and

<<that is about what her face looked like.
