Huh?
Selected out, you mean? Yes, but it's not hereditary. If it were and it killed people before reproducing or made them unable to have sex or raise children, it would have been naturally selected out. The genes would not have been able to pass on.

Then we agree: without a natural-selection level difference the gene expression makes, not much happens! That means that the foreskin isn't exactly a great contender for NS-mediated evolution, right?
-
I don't know what you mean? Obviously the foreskin evolved by natural selection. How else would it have come to be?
-
The foreskin came to be because it did. To claim every part of us is specifically optimized by evolution isn't correct. Some things just are good-enough and are there because they didn't get overly in the way.
