If we described domestic terrorists (bomb makers, mass shooters, killers, etc) as 'that waste that killed a bunch of people in X during Y' and never /ever/ published their names (in the news anyway, court transcripts would need to show them) then it would make those actions a lot less sexy.
In that same way, we should also call the extremists in the middle east that; possibly picking an arbitrary flavor word that is of no relation to them just so we can make a distinction. There are /quite/ a few extremist groups in that area of the world.
