You and caribny both ran out of ideas and are helping ISIS with this division. This is what ISIS wants.
ISIS wants people like YOU to do nothing, so that the demagogues and bloodthirsty warmongers like Giuliani take control.
Kari if ISIS explodes a bomb at Penn Station at rush hour and 100 are killed and 500 are injured, do you think that people will be interested in engaging in philosophical chatter that it is just a few thousand goons. No their attitude is that these people are interpreting teh Qur'an and using this to justify their actions. Pointing out that the Old Testament is equally violent solves nothing, because there is no group of Christians who interpret this literally, and who act on this.
If you do not want this, then you ought to be offering ideas as to how mainstream Muslims can reduce the effectiveness of the Islamists, and not just the terrorists.
As a Muslim you ought to be embarrassed about to what happened to Malala. This is the fate of many girls in many Muslim societies when they want access to education. This isnt ISIS, as ISIS was NOT around when she was attacked. This could be Pakistan, Afghanistan, Somalia, northern Nigeria, and other places.
