It is a thing, the youngest to have it done is 17.
Accusing people concerned with the idea of removing a child’s genitals to some sort of pedophilic thought is so out-of-this-world crazy. Would you say that to people who are against female circumcision? Those are also “thoughts about children’s genitals”. The very idea that you’d remove them at all is “thoughts about children’s genitals”.
Being concerned about removing future, of-age sexual pleasure and function from a child is not pedophilic in any way.
