Since this author is leapfrogging over history allow me to add that the Greeks of the 19th Century fought and defeated Islam.
This article and author are pure a$$-wipe.
Please note that I am not comparing Bronze-age Greeks to Islamic terrorists. I'm pointing out moral failings that are wonderfully illustrated in Homer (unchecked passion and excusing everything by invoking the gods) and explained by later philosophers. I then observe that those moral lessons certainly tell us something (but not everything) about Islamic culture and terrorists that come from it. Note that I mention Islam's envy for us, the heirs of the Greeks. In a longer piece I would add that they hate us not for our vices but our virtues.
The classics can teach us much!
