The real difference is that Muslims believe in killing as part of their religion.
I've spent a good portion of my adult life in third world muslim crapholes and you have to realize that many muslims are not only uneducated but that 20 years ago or so many of the were still rubbing sticks together to make fire. Many "educated" muslims I knew couldn't read a map, or use the simplest handtools. Muslims that drove vehicles down the road at night flash their lights on and off so as not to "wear down the battery". Egyptians painted the tails and wingtips of their F-16's orange, so that they could tell the difference between their F-16's and Israels (apparently, there is no orange paint in Israel). And these are just a few examples from progressive muslim states. Many Americans and Europeans just cannot understand what 3rd world truly means.
