Ban it for those under your local age of consent (usually 18).
I am uncircumcised and I can say that for myself, yeah that inch or so of skin is pretty damn sensitive, a good deal more than the shaft but less than the head*. Its easy to keep clean, when I take a shower or bath, roll it back, apply soap/gel, rub gentle, rinse....its not hard (unless you rub too much), takes a few seconds every day, you only get dick cheese if you dont wash for several days. As for the callousing/desnsitising of the head, it can happen depending on several factors. mainly where your junk swings and what it rubs against.
It is mutilation of a person who cannot consent. Yes if the purpose is genuine medical then have at it but that is a very small percentage of the number of circumcision.
I get that it is tradition for some groups but we *do* choose to not respect religious traditions that conflict with our social and legal values, off the top of my head parts of Sharia law comes to mind and this should be one of them.
If the person chooses to do so at the AoC then that is there choice and I respect it.
As for female cicumcision, I wont even pretend I think of it as anything less than child abuse, pure and simple.
*this part of the post was a lot more graphic pre-edit but I figured we are mostly adults here and can figure out the situations where +sensitivity is good but to the guy who said "do you really want a more sensitive dick?" I say yes, I dont have problems with staying power thank you and even if I did cutting parts off seems drastic compared to learning willpower and self control, Im sure you could find a partner who is happy to help you learn.
/edit: Really you're gonna go with it stops the spread of Hiv...a little well christ man thats what condoms and sex education are for. Surgery shouldn't be considered any sort of answer to the problem
