I was just trying to think of body parts with little or no use. I could have suggested a toe nail or hair, but they're not made of skin, so probably not a fair comparison.
We do wear clothes these days, making that function somewhat redundant.
My understanding is that female "circumcision" or Female Genital Mutilation, is totally different from circumcision, and not really comparable. While circumcision just removes excess skin, FGM removes the most sensitive part of the female anatomy.
I think the argument that circumcision reduces sexual pleasure was debunked in 2015.
I fully agree. But I believe that after sin entered the world, things deteriorated. So as people started wearing clothes, the purpose of the excess skin on males wasn't so important, but the consequences of disease was moreso. I don't think this was the primary reason God gave circumcision, but I believe there may be health benefits, and certainly that God would not command something that was harmful.[/QUOTE]
