One of Mordechai Gafni’s (aka Mordechai Winiarz) many victims has written a telling account of his manipulations. She vividly illustrates the moves of this psychopathic manipulator. Read it. It will help you understand the many allegations swirling around him, most recently featured in the articles by Mark Oppenheimer in the New York Times and Tablet Magazine (also here).
Normally, I would excerpt such a post to give you the flavor, but I cannot do it justice. You have to read it to get how he made his moves and succeeded in sexually exploiting many females including minors without ever getting convicted. It is well worth reading even if you are not interested in Gafni, just for an education in the methods of sociopathic manipulators.
Kudos to Rabbi David Ingber for initiating an online petition against Gafni and catcalls to Whole Foods CEO, John Mackey, who keeps right on defending and funding him. Kudos also to Esalen Institute for initiating and inquiry that got him to drop out as a teacher.
