WHAT ???????????
Are you actually comparing circumcision to cancer ?
No he's comparing AIDs to cancer and circumcision to mastectomy.
Shocked are we?
I think we should remove all organs from the body, at birth, that may one day become diseased. HIV, cancer, whatever. If it is removed at birth, then he or she won't remember the pain later, and it's easier than doing the procedures at an older age. The organs that should be removed includes breasts, ovaries, testicles, and skin. All skin. We don't want to be susceptible to skin cancer. After all, we know better now, we have the studies. Oh, leave in the tonsils.
This makes as much sense as the argument you put forward.
