You think the witch-hunt mentality is dependent on Christianity? Oh boy...I doubt there are many English-speaking articles on the witch-hunts that have occured in Scandinavia in recent years but just take my word - you're wrong.
Besides, there is no mention of Christianity in the article. You're the one making the inferences without any logical foundation.
He's arguing that it was Christian-based because it was an attempt to scapegoat Satanism. There is some initial truth to that considering the early propogators of the satanic ritual abuse myth were fundamentalist Christians, see the now-debunked book Michelle Remembers. The problem with his argument is that the moral panic was initially largely just for money and publicity. It's hard to argue that LaVeyism, (supposedly the "religious competitor" in question) is a large threat to Christianity, nor were any of the scapegoated followers of it (most likely they were Christian as well.) So yeah, it's a baseless and silly attack.
