i dont care how young it is done, I believe we remeber it.
it plants a seed of pain that isnt necessary isnt a baby .
Here they are, new to the world, have no ability to speak, defend themselves, and completely rely on us for any and all support.. and out of the blue, they get thier body cut off.
scary, painfull, traumatic.. you name it.

That would be the fault of the parents, not the foreskin..
