Is your objection because the diaspora being written about was not Jews, but Muslims?

yep.. and with a terrorist connection at that -- it was the first time I'd seen it used in that sort of context, and I just found it jarring; if it has become commonplace, so be it.

(I guess I'm somewhat surprised, in an age when you can hardly utter once-innocent words such as niggardly, to find somewhat of a counter-example. otoh, there's a completely different mechanism at work.)
