No it doesn't. Or at least, nowhere near as often as it is blamed. Pretty much every so-called "religious" war is actually about something else - usually the old classics: land, resources, money or power. Or any combination. Religion makes a fine recruiting tool, and an great way of stoking up hostility - witness the reactions here to a probably fake Muslim (with the emphasis on Muslim) plot. But that is not what such wars are about. To take a classic example, the conflict in Israel is about land and resources, not religion.
In this case a couple of things spring to mind:
"Operation Trojan Horse". Seriously? I would expect a radical Islamic plotter to give the plot an Islamic name, not that one. And I'd expect a serious plotter to give the operation a name utterly unrelated to the operation itself. That's a name I'd expect a not particularly bright Westerner to give to a plot, particularly if they wanted to shout "plot" really loudly. This is most likely a bit of ****-stirring from a Right-wing group of locals. The only question is whether they believe it themselves.
Also, as I said, the magic word here is "Muslim". There are a number of Christian academies trying to bring in fundamentalist Christianity, but no-one seems to care much about that.
