Either the situation in Iraq is much worse than what has been reported so far, or Dexter Filkins of the New York Times has managed to define down a euphemism for genocide.

In northern Baghdad, Shiite families arrive regularly at the Muamal Sadr refugee camp, fleeing the ethnic cleansing that is transforming the mixed cities around Baghdad.

There's no doubt that there is a new problem of people leaving their homes to live in refugee camps in other neighborhoods or towns, but ethnic cleansing?

Much farther down in the article he says, "Full-fledged civil war, with widespread ethnic bloodletting and mass migrations, has not yet come to Iraq."

Is it possible to have ethnic cleansing without both widespread bloodletting or mass migrations?  Paint me confused.
