The whole "do not change the creation of allah" is not what makes me think this is stupid. I can somewhat get why a religious ideology, used to control the masses, wants to eliminate individuality and make people preoccupied with the "next" world so much so that even day to day mundane activities must be damned impermissible or disdainful. There is a very good explanation and reasoning behind this, and this is why Islam isn't the only religion that has had and still has these kind of rulings and regulations.
What bothers me more is how, without any real logical or reasonable reasoning, inconsistent this principle is applied. You remove hair from your armpits and private area (actually, removing hair from women's private area can cause a lot of infections and other complications especially for some who are more sensitive than others. More so in warm and damp environments), even your arms and legs, but god forbid you touch your eyebrows. You can't tattoo your body, or do any other cosmetic alterations to it (plastic surgery or other culturally bound practices such as filing teeth), but hey lets cut the foreskin and clitoris. That is not at all risky, and in no way alters the creation of allah or interfers with normal human sexuality
