OK then it would be fair of me to ask you this question...
If I choose to surgically alter my daughter, have her labia removed and I tell you I will be doing it at birth, would YOU feel something..a little pain..anything? Afterall it doesnt' "affect you"..
Your daughter's labia is something I would not compare to a foreskin first of all. I am not at all interested in the discussion of comparing the apples to oranges argument that anti-circ individuals bring up.
Removing the labia above all else removes her will to even want to have sex in most cases and it has multiple detriments and side effects. There are many peer-reviewed studies on this. This is why Female Genital Mutilation is against the law in many places. There is a difference.
Circumcision however is 100% legal worldwide. Millions of men have had it and they live perfectly good sexual lives. I have though I was cut as an adult. My dad has cause he has like 10 kids. I'm not saying that everyone should be circumcised, heck I dont even think the majority should be circumcised. But if parents make a choice they make a choice and over thousands of years this choice has been made billions of times and it has yet to be proven to be overtly detrimental to any man. Like anything anomalies do arise.
To answer your question though...I would not feel pain. I would feel remorse that you have to make this comparison with your daughter in order attempt to prove a point to a stranger. I would also report you to the authorities cause you just broke a law.
