I just read this in Réveillez-vous!, the French edition of Awake! (August 2009 issue, page 3), a JW periodical:
Quand elle est approuvée par la loi, la discrimination peut mener à des atrocités comme la purification ethnique et le génocide. On trouve un exemple de tentative de génocide dans le livre biblique d'Esther.
which translates as:
When approved by the law, discrimination can lead to atrocities such as ethnic cleansing and genocide. One can find an example of a genocide attempt in the biblical book of Esther.
If you read the Bible, you'll notice that the target of this attempt was the people of Jehovah - i.e. the Israelites. And this attempt failed because of Esther.
Now, isn't it symptomatic that, among the many succesful genocides committed by the Jehovah-sponsored Hebrews, or Jehovah himself, the JW choose this failed attempt to illustrate their point?
