WeBuilt, in answer to your question: At what point do you judge that an act of non-consensual mutilation which brings with it undeniable negative consequences is a step too far?
'Non-consensual': In general our experience leads us to believe that the vast majority of our sons when grown up will be happy that we consented to circumcision on their behalf.
'Mutilation': People in our community don't define it thus.
'undeniable negative consequences': I don't believe that there are. The only potential consequences which have been mentioned are pain and possible loss of sensitivity.
Pain, especially nowadays in an era of easily available anaesthetics, is usually minimal. Any slight amount of pain will be quickly forgotten and is outweighed by the lifelong benefits.
With regards to loss of sensitivity, this would not be severe, and is only an issue if you see the maximisation of sexual pleasure as a goal to be aimed for in and of itself. I repeat that circumcised men have normal sex lives and the same fertility rates as non-circumcised.
I don't fully understand your points about murdering and punching people in the street; it reads as if you think I am trying to persuade you that circumcision should be done within your own ideological framework/worldview and according to your decision-making criteria. I'm not; I'm trying to give some insight into the perspective of some of those who do routinely circumcise, but that takes place in the context of a different worldview and a different set of decision-making criteria.
Finally, you said: I just can't understand the desperation to mutilate babies for no actual reason and try to justify it by saying "oh, they'll probably be fine - even though they've had thousands of sensitive nerve endings taken from them without their consent, it probably won't make any difference - it's not like I've chopped their arm off."
That's blatantly not what I am saying and you know it. I don't have to justify it; male circumcision is currently not illegal in any country.
I do have actual reasons: circumcision is mandated in my religion and is also a cultural norm which people are happy to adhere to.
