I think that all kinds of genital mutilation are an abhorrent, primitive, despicable practice. I am happy that by now we have come to a point where pretty much everyone agrees that female genital mutilation is a criminal practice that is completely unacceptable. But as soon as it comes to cutting off the foreskins of little boys, often because some god just needs lots of foreskins, people start to give all kinds of excuses.
In my opinion, this practise should also get outlawed, no matter if it is done for religious or other reasons, with the only exception if there is some kind of medical reason in a specific case.
Everyone is free to decide to cut off whatever body part they like once they are grown up. Until then, I consider that practice bodily assault.
