Ah, please don't put words in my mouth. I have not said "that most humans do not have 10 fingers, and 10 toes". What I have said is that some children are born with more. Who are you to tell me that God did not give these children an additional digit? You are merely taking an observation based on frequency in other children, and somehow interpreting that as God's will. Is that appropriate?
I don't think that dismissing the comparison because it does not involve sexual pleasure is at all an accurate move. You make the comparison yourself to singing fingers, acknowledging that fingers are a part of the body with a high density of sensory innervation. By your own attempts at making an analogy, you acknowledge that mine has to at least be as comparable.
Your basis against circumcision in this post continues to be on the alleged "decrease in sensation" caused by circumcision. Again, studies do not strongly support this claim. Indeed there are studies that do come to that conclusion, but (as I have already provided) there are studies that come to the opposite conclusion. The majority of studies on the subject come to the conclusion that there is no difference. If this is what you base your argument on what makes circumcision "unacceptable", I have to make the point that the evidence isn't there to back it up.
My intent was not to put words in your mouth, if that is how it was perceived. I'm just a little surprised. You don't think that there is a common layout for the human body, and that common, intended layout (not rare outliers or differences from the normal) includes 10 fingers and 10 toes. I had assumed everyone accepted this. It is surprising to see someone say that it is not the normal for a human to have 10 fingers and 10 toes, that really is a different perspective. If you don't feel that the normal human body layout includes 10 fingers and 10 toes, I'm not sure what to tell you.
My basis is both the decrease in sensation, and the fact that it is surgical removal of healthy tissue. Surgical removal of healthy tissue sure sounds like harm to me. Surgical removal of a healthy index finger would sound strange to people, but surgical removal of the foreskin, which can feel a lot more sensation, is not (yet) accepted as strange by many. It is more comparable to removal of one of the 'normal' 10 fingers, than to an 'extra' finger, because it is not an 'extra' body part, it is a standard body part. I see you don't accept that there is a common layout for the human body (which can have outliers), so you likely won't accept my argument, but that is what I have to say about it.
