It is wrong to protect one sex legally from having their genitals mutilated, yet routinely hack away at infants of another sex. Female genital mutilation is abhorrant - so is male genital mutilation. No person, regardless of sex, should have their genitals butchered against their will. When you circumcise a boy, you are forcibly amputating a healthy portion of his anatomy without his consent - you are violating his human rights to bodily integrity.
If an adult male wishes to be circumcised, that’s his choice - but it needs to be his choice. When you mutilate an infant, you are taking away their choice to their body, the same choices that you profess you should have.
Children are not dolls. They are not your property to do with however you see fit. They are people - treat them as such.
