I believe you.

> I'm saying the state of Greece's economy, embedded in a global economy, is where we should look.

This is where I think you're jumping the gun. There are insane people everywhere. Sometimes some of them do brutal things. That's a sad fact of life. Implicating his Greek-ness will, I believe, lead to unnecessary bitterness against Greeks.

I'm sure you've come across Grice's Maxim of Relevance. Going by that, I tend to include "Greek" if his being Greek led to some racially motivated action, I'd include "male" if his being male led to some sexually motivated action, etc.
