When the gangs are driven by the belief of their so-called “religion” in their actions, it is appropriate for their religion to be named. The Romanians aren’t acting in the name of their religion, if they even claim Christianity. The Islamics use their religion as justification of their actions.
The sort of false equivalency you bring to this issue is characteristic of the arguments many on the Left bring to discussions of the problems with Islam.
I didn’t bring any false equivalency - I merely examined the logical use of language used in this case, nor did I state my opinion.
Do we identify people by their religion or by their nationality?
In my opinion we should generally describe people by their nationality, but in the case of Islam there is a strong case for using their religion as above all others, muslims seem to identify with their religion first and their nationality a poor second. I suspect it has a lot to do with the islamic concept of the ummah.
As far as this particular case goes Islam clearly has many ways of encouraging its’ followers to consider infidels below them and that clearly played its part, though I suspect the backward culture of Pakistan and Afghanistan played just as much a part in it.
