Oh for crying out loud, that is such a Greek attitude. We barbarians are perfectly literate. Just because we don't read or speak Greek specifically doesn't mean we can't read anything. Can you even read Amharic? I can, but to you it all sounds like "bar bar bar" whether I'm speaking Amharic, Egyptian, or Farsi.
You need to look beyond your own borders and realise that "literacy in Greek" ∈ "literacy".
