I think people also keep missing an important point, as a man who is a fan of his healthy friend down there, are you really ok with taking any chances on an unnecessary procedure?
Also the covenant for the Jews, was the 1st one not working proof that snipping foreskins isn't going to do anything with your god?
Hell the fact only boys do it just makes it more painfully clear this is nothing a human idea and not something divinely ordered; do you believers believe women are of no worth in their gods eyes. But that's a long topic of chauvinism in the old testament and of really all old religions.
