> And even so, how in the world does 1000-year old interactions threaten your world view of Swedish cultural/racial purity and its relevance in modern times?

I don't know, ask the people "[franticly searching] for anything and everything which can be used to 'prove' that Sweden [or anywhere else] has always been a melting pot of different cultures". They're the ones implying this is relevant, and that Vikings not being influenced by Arabic culture would somehow make white supremacism less stupid.

Also, to add to what several other people have said, modern Arabic, even more so that most illegible scribbles^W^W cursive scripts, is notorious for any random collection of curves looking like a word; I think we're up to three different cases of someone catching a fish with "Allah" written on it's scales. Somehow, I doubt the situation with older Arabic writing systems is any better.
