Of course it was.
There's that nice, broad brush, not to mention the abysmal vocabulary. So faith, generally, led to this bombing? Religion, generally, led to this bombing?
Left-wing sympathies or politics are hardly ever blamed for North Korea's general state or their belligerence. When a country goes to war for oil or money or power, you never hear anyone talk about 'secular desires' being the driving cause of their war declaration.
But if an Islamic radical carries out a bombing, it was 'faith' and 'religion' that was the culprit. Not 'Islam', or a specific variety of Islam, but 'faith' and 'religion' generally. And it's done so people can feel confident in going on to attack and criticize the religions they dislike, but which aren't responsible for this bombing, while they can remain quiet about the religion that it's not politically correct to criticize too strongly.
