It’s a little weird to call out specific religions here for behavior they all engage in.
First, some religions have worse track records than others. Second, your imploration was to "name a more iconic duo", which you got. Third, what's actually weird is FGM and kiddy fiddling.
religions are bad but as long as we live in a world where they are voluntary
Religion isn't voluntary because it's perpetuated by the indoctrination of children.
