Another study I posted talked about pricking genitals with a needle in a symbolic gesture.
Of course, this is also awful, wrong, and unnecessary, but it is I would say comparable in terms of potential side effects/complications etc to castration.
Anyway, the issue I think is that people are deliberately harming and mutilating children based on a religious motivation. That's what makes them similar.
I can see both sides, for what it's worth.
Practically speaking, I think a very clear, very strong line of 'no hurting babies for religious reasons' might make the whole issue easier to address? No getting lost in the thickets of whether infibulation or circumcision are worse etc, just a very straightforward banning of any and all mutilation of children.
Jesus, I can hardly believe anyone would try to justify it.
Don't hurt kids! That's it!
