IDF soldiers do not rape Palistinisn women are racists?

Here it is alleged that Israeli Defence Forces soldiers do not rape Palestinian women because they are racists.

This is not a joke, who could make this up? Perhaps it has not occurred to the author that the lack-of-rape of Arab women by Jewish soldiers is because the I.D.F. are too fastidious.

• A research paper that won a Hebrew University teachers' committee prize finds that the lack of IDF rapes of Palestinian women is designed to serve a political purpose.
  The abstract of the paper, authored by doctoral candidate Tal Nitzan, notes that the paper shows that "the lack of organized military rape is an alternate way of realizing [particular] political goals."
  The next sentence delineates the particular goals that are realized in this manner: "In the Israeli-Palestinian conflict, it can be seen that the lack of military rape merely strengthens the ethnic boundaries and clarifies the inter-ethnic differences - just as organized military rape would have done."
  The paper further theorizes that Arab women in Judea and Samaria are not raped by IDF soldiers because the women are de-humanized in the soldiers' eyes.
  The paper was published by the Hebrew University's Shaine Center, based on the recommendation of a Hebrew University professors' committee headed by Dr. Zali Gurevitch.
