@lane_r2018 It's not worth discussing further, but that point isn't exactly a slam dunk. Many Christians (especially in America) choose to circumcise their children: https://en.wikipedia.org/wiki/Religion_and_circumcision#Christianity
With your same reasoning, religious circumcision would also be considered "mutilation of children". The reality is that decisions made around a child's health and their body should be between the parents and their doctors, and in accordance with local laws.
