First off, studies show that babies feel pain and process pain even when in the womb. For many years doctors have assumed otherwise and have routinely operated (open heart surgery, corrective eye surgery etc etc.) on under one year olds without any anesthetic. (In 1988 the AMA finally changed their policy). Talk about trauma!
Second, if we take the action of circumcision outside of religious context, it seems awfully barbaric. Try explaining to someone from another planet why we chop off a very sensitive part of a new born baby’s anatomy. Many in the US claim the “tradition” argument. But circumcision became a trend in the mid-eighteenth century due to a campaign to stop boys masturbating. It failed in that.
I would argue that circumcision is pure child abuse that causes stress, anxiety, encoded trauma (remember traumatic stress comes from being in a state of helplessness) and should be banned immediately. If a fully grown adult man or woman wants to mutilate their body then that’s up to them. The only way babies communicate is to cry and that is what they do when you mutilate them.
Here is a funny clip about circumcision with serious points.
