Sharia is not mainstream Islam in all parts of the world, Keith. For instance, it's not mainstream among Muslims in the US. And there isn't only one way to interpret Sharia law. During the Ottoman Empire, for instance, the only punishment for adultery was a fine, and four eyewitnesses had to testify that the adultery took place, which meant that it was very difficult to establish guilt. There is no uniformity among Muslim governments about how Sharia is applied. As I said before, you really have no idea what you are talking about.
