There have been many, many reported cases of stoning to death in countries such as Afghanistan and Iran, let alone those that have never been reported. The crime often being, for a woman, to be seen outside her house with a man who is not her husband (her owner, I should say). In African Muslim countries, they also have the nice custom of burying people alive for similar "crimes".
One convenient thing with Islam, just like with Nazism, is that it doesn't take long to figure out on which side evil stands. Here you have blatant, undisguised evil. It must be destroyed completely, period.
