Yes, of course it's wrong. But then the media should either stop using "Muslim/Islamic terrorist", or start using "Christian terrorist" or "atheist terrorist" too. I don't know the numbers, but aren't a large number of people in the West, and especially Scandinavian countries Christians in various denominations? Also, isn't a large number of those who identify as right-wing Christian?

Radical anything is dangerous, I think, whether it's politics, food, alcohol...
