The other day I linked to Daniel Levy taking Benny Morris to task for "attempting to give a veneer of intellectual respectability to the well-rehearsed propagandist whining of apologists for Israeli policies and Israeli settlements." It was a great piece that you should read.
Since then Morris wrote a lengthy rebuttal which ends in this way:
Lastly, Levy objects to my occasional use, in the past, of the word "barbarian". Well, how would he define societies that carry out or condone the murder of thousands of women each year simply because they look the wrong way at a man or glance at the wrong man or dress the wrong way (the Arab world); or who practice mass coerced female genital mutilation (Egypt); or which put men on trial for homosexuality (Egypt, Saudi Arabia, Iran, etc.); or cut off the arms of thieves (Saudi Arabia) or stone women who are charged with adultery (Iran); or kill masses of fellow Arabs or Muslims, often in funeral processions, in suicide bombings (Iraq); or which dance on rooftops or hand out sweets to children to celebrate the blowing up of a bus crammed with civilians (Palestine); or who shoot down and torture many thousands of civilians who say they merely seek freedom (Syria)? If Levy has a better word, let him offer it.
So as long as you're not generalizing, then, Dr Morris.
