Is circumcision ethical?

[MarkFL]

I simply mean if an adult wants to undergo a procedure that alters his/her body, then fine...no problem here.

I would argue that a baby has no religion, it is another person's religion (presumably that of his parents) that is being imposed. It is a barbaric iron-age practice that should be abolished, IMHO.

One could argue that there are vestigial parts of the human anatomy that we are better off without since evolution is a continuous and ongoing process (e.g. widsom teeth, appendix), but I would not put the human foreskin on such a list.
