> most of them seemed more anti-Christian and anti-Islamic than anti-Jewish.
This makes a measure of sense:
1) The Christians wiped out heathens in large number back in the day. Look up Charlemagne's "Bloody Verdict of Verden" where he reportedly killed thousands of Saxon heathens for refusing to convert. Scandinavia was converted top-down at the point of a sword. This tends to annoy people, and when it comes to religion, annoyances seem to last. Witness how many Christians are still cheesed of at the Jews for "killing Jesus."
2) Interactions between the Norse and the Muslims happened, but there's little record of any real conflict. On the other hand, islam *today* poses a serious threat to heathens and pagan. Telling an Asatruar or an Odinist that his choice is either conversion or death is a good way to get popped in the nose.
3) Jews: except for the whackos, modern Asatru has nothign much to say one way or the other about Jews, anymore than about Buddhists. They pose no threat, and never did.
The Odinists who hate the Jews are really just carrying over Christian anti-semitism into a wholly different religion. This ain't new... witness all the non-Christian things that got imported into Christianity.
