That is the Old Testament, and if you disagree with passages in the Torah, you should talk with the Jews about those laws that governed the Israelites.
Some Christian groups still believe all that still holds, but most Christians believe Christ fulfilled the Law and instituted a new Commandment, "that ye love one another even as I have loved you." He forgave the woman taken in adultery who was about to be stoned and prevented the stoning. (He also commanded her to "sin no more.")
These are the Christian traditions, forgiveness and love, and throwing up old Israelite laws that a minority of Jews and Christians still believe in is the same tactic that you are criticizing the Muslim critics of using, condemning the whole for the views of a minority.
However, I do agree with a lot of people here that the "minority" of Muslims who believe in killing or enslaving Infidels (you, me and our families and friends) is a lot greater than you think, especially if you add in the Muslims who acquiesce in this murder and slavery.
And don't kid yourself about the latter. It is Muslims who still continue to practice slavery.
