I don't know if this is allowed here, but I didn't know where else to go. My sister is planning on getting her newborn circumcised. Needless to say, I'm trying to talk her out of it, but I'm failing. I need the best information and articles you have in your tool belt that clearly refute all the "pro circumcision" arguments, as well as arguments that show circumcision is a bad idea.

It seems her main argument is that it is a zero sum game, and that it doesn't matter either way. I can't understand how that leads to a conclusion of "let's mutilate my baby", because that's not how the null hypothesis works, regardless I need a better counterargument than "that's not how the null hypothesis works".

While I'm educated on the matter enough to make a coherent argument, I think someone who has done more research on the subject would be able to pack more punch.

Appeals to emotion and appeals to logic are both welcome. A quick search on the internet reveals many counter arguments, but I want ones that have already been selected as the "best" ones. So, give me the best you've got.
