Well said, my husband was circumcised at 13 as a punishment for being caught masturbating and it took months to heal and was extremely traumatic, and the foreskin is a very sensitive and important part of the penis. It would be like removing the clitoral hood for a woman.
Circumcision to anyone who isn't an adult able to consent, is abuse and mutilation. I don't care what your reasons are, religious or otherwise.
