I may be the only one who was bothered by the use of diaspora in the context of this article, but I'd be more willing to accept that if I thought anyone else had read it.

I read it. So what's your gripe? A quick google around the web shows that many journalists are writing about a kind of Muslim diaspora (Turks, Moroccans, etc.) in Europe, and how various terrorist organizations recruit from young men among them.

The Spanish authorities traced a document found in the van near the Madrid train station to Moroccans living within Spain, longterm: a kind of diaspora.

Is your objection because the diaspora being written about was not Jews, but Muslims? It seems that the meaning of diaspora has extended itself into other ethnicities and religions.
