I don't know if there are any statists on that, I've never seen any.
Most times dad wants it done because he is cut and he knows no other way. To not cut his own son means acknowledging that what happened to him wasn't needed and most men choose not to look into it because that can bring up all kinds of buried unwanted feelings.
Sometimes intact fathers want it done because their experience was one of being made fun off in the US or like many they experienced incorrect care growing up and now have a few issues from that, not realizing that their issues are normal and are treatable. Sometimes they assume its genetic because brothers may have the same issues (due to the same faulty care)
I think an intact father who has never had issues would be highly unlikely to want his sons to be circumcised.
Women in the US on the other hand, are simply used to seeing cut so the other is the unknown and often by extension thought of as gross. This may also be due to the belief in the myths that are so prevalent across the country. They may fall back to letting their DH decide-which if he is cut he often has no more idea than she does.
Both parents frequently buy into the myths and rhetoric of it's cleaner, better and never really look into it. In the US given it's seen as normal so this would be the easy road to take.
Whoever wants cosmetic surgery done should defer to the parent who doesn't, as the default position. Medical reasons are different, but RIC is not a medical treatment.
