"I can see what you are getting at, Jim, but did any of the perpetrators of the above attacks justify them by saying they were doing it in the name of Christianity?"
Does it matter?
Breivik made a point of describing himself as a "Christian Militant" - does that make his massacre a "Christian" one?
In the end it doesn't matter a toss.

1. Yes it does matter. If people say they are committing a crime in the name of (enter your own whatever) then it is fair to say it is a (whatever) crime.
2. As Breivik made the point that he was a Christian Militant the implication was that he committed the crime in the name of Christianity. So, yes, that was a Christian hate crime.
3. In the end it doesn't matter a toss to the victims. But it does matter in the reporting of such crimes as (whatever). If it is an Islamist hate crime, let's call it that. If it is a Radical Christian hate crime. Then call it that as well.

the Woolwich murder was not a political act - it was the work of a number of twisted bastards who justified themselves by claiming religion to be their reason.

The massacre of Jews, Gypsies and Poles in WW2 was also an act of a number of twisted bastards as well. But we waged war on the whole German nation, not just the twisted bastards. When the population fails to control it's own extremists someone else needs to intervene. Whether that should be the UK, the US the UN or someone else is entirely another debate. And, yes, the same should apply to everyone!
