It's tied to religious dogma and no serious politician in North America wants to tackle the issue.

FGM at least got a ban but that's because no major religious group publicly support it.

Male genital mutilation gets religious support widely and publicly. Abrahamic deity loves to eat foreskin and nobody wants to see Almighty get hangry.

Those who dare to speak within faith groups say it should be an adult decision, not imposed on child. Kinda like Anabaptist who don't deny the religious significance of the baptism ritual but they don't impose it on a child.

Nobody cares what non-religious or non-abrahamic religious communities have to say on the topic so they don't bother getting involved in the debate. Except atheists who don't have to worry about defending their own dogma after questioning circumcision-lovers.

Most likely, the smart secular doctor will say it should be between a doctor and the patient and their family. Not the government or random people. Same answer most give on abortion and gender dysphoria.
