It's insulting.
My ancestors were barbarians. Some of them still are. Before that first cup a' joe hits, you might even say I am one myself. Oh, yeah, we may occasionaly destroy a civilization, burn the odd monestary, villiage, city, whatever. We may even plunge a continent into a thousand years of stagnation from time to time.
But we do have a certain sense of dignity and style. And we know how to compete in an open marketplace, even if that does sometimes require a bit of sacking and pilliage.
