I don't get the false equivalency between your arm and your anus. The anus is neatly tucked away, and is supposed to handle fecal matter. You're not going to accidentally rub your unclean anus on some food or in your face, unless you cook differently than most people and is more flexible. Would you put your face in your shoes for hours at a time, or rub it on the ground when you walked? Probably not, but thats no problem for the feet, because they're a different body part with different strengths and requirements.
