If you're a Libyan protestor, then what better way is there to demonstrate your views and gain local support than to portray the Dear Leader as a Jew with a Hitler mustache.
And you thought that Muslims weren't creative, you Islamophobe you.
This also shows the naivete of those who insist that the demonstrators in Egypt, Libya and elsewhere in the Middle East are pro-democracy secularists. They may be pro-democracy insofar as they want the will of the people to be heard, but given their worldview, their frame of reference, their core assumptions about the world, if that popular will is heard, it will likely result in huge victories for the Muslim Brotherhood and similar pro-Sharia groups.
It's the perfect recipe for a hell on Earth.
