Sorry for Raymond's prejudiced reply. As I said to him, I don't believe women were excluded from the covenant of circumcision in the bible. It was just the covenant sign was written on the man. Zipporah's example in Exodus 4 shows us that even though women couldn't be circumcised, they still played an essential role in ensuring the covenant was kept.
I agree that society's standpoint often differs from the Christian one, but based on God commanding circumcision (i.e. of the man/foreskin, not Female Genital Mutilation), I think describing the covenant as "mutilation" or "messed up" (e.g. by some in society such as certain human rights groups) is going too far.
I hope the above didn't sound disrespectful.
