How can circision be considered genital mutilation when God commands it to Abraham and all his descendants?

It is mutilation no matter how you explain or justify it. It is old Testament and not meant for Christians. Although many Christians will select old Testament verses to justify what they want, it is still wrong. There are many rulings in the Bible that are not followed today and that is because people are more educated and sophisticated. The Bible has some good advice, it also has some really ignorant- dangerous practices.
