First of all can we stop with the whole "it's a male issue". It's not a male issue, it's a human issue. I'm a man, a woman's opinion on this is just as valid as mine.
Secondly, the comparison to ear piercing is a false analogy. Ear piercings heal relatively quickly if you don't maintain them. A better comparison would be giving your baby a tattoo or a decorative brand. Even then not so much because you can have a tattoo removed, you can't grow a foreskin back.
Would you tattoo your newborn baby?
Cutting bits off baby boys bodies for religious reasons is unjustifiable in this day and age. Completely unnacceptable.
The only way these kind of things are shown for the barbaric practices that they are is to take a stand against them. Good for Iceland, hopefully, we will next.
If the best argument you can find to support cutting chunks off a babies penis is "it's always been done" and you are still supporting it, then you need to take a long hard look at yourself.
