My main concern here is that if you took a representative sample of Germans - no more than a few hundred thousand people, and pretended those were filthy immigrants then asked the same question- does this group pose a tangible threat to existing citizens (never mind the fabric of German culture), the answer would always be yes. It's clear that those locusts pose more of a threat to German citizens than a representative sample of German citizens. I think that's the nuanced liberal's view. (which, to me, beats the nuanced conservative view.)
