Religion of peace

When it is a basic tenant of your religion that it is OK to denigrate and kill non-believers (read Jews and Christians) is it such a stretch to think that to some within your religion other “believers” qualify too?

Many Muslim leaders in the Middle East and elsewhere have spent generations instructing the populace that those that do not believe as you do are less than animals and do not deserve to live. It is on the placards at every demonstration, “death to the non-believers”. As any wildlife specialist can tell you, when push comes to shove eventually even wolves eat their own. In this case, as the French would say, bon appetite.
