To maintain that circumcision is harmless and even beneficial is to insist that injuring is safe and healthy. Or that deconstruction is constructive. This view needs a good deal of constructive criticism.

Actually, circumcision is a dangerous intervention that has proved to present serious health hazards. Otherwise, if circumcision was safe and harmless it would not need to be justified.
