personally i find even very selfish from parents piercing girls ears for earrings (like at least 80% parents do here around me), chopping skin of my son would be even crazier idea

if she wanna wear earrings or he wanna be circumcised they can make their choice when the time is right, but it's not up to me, i think same even about parents forcing their own religion onto their children and baptizing them

and i am not some theorist, i have actually both of those children
