this case was a real outlier. It was done to an adult, it seems to have been done by a poor surgeon, and it was done at the victim's own request.
You can't draw any universal conclusions from such cases. Operations do go wrong, but that shouldn't be grounds for banning all operations: most male circumcisions go just fine. The rationale for doing them isn't the same as for FGM: this man wanted it done in part to improve sexal pleasure; FGM is done for exactly the opposite reason.
