…there is never, ever an excuse or justification for extortion. No one, not our brother, nor our son, nor our rabbi, can ever attach conditions of any kind to the delivery of a get. Not a financial condition, not a child custody condition, not any condition of any sort. And we have to possess the moral vision and religious courage to loudly and publicly label any effort to impose such conditions for what they are — extortion — plain and simple. We can’t let ourselves be fooled or hoodwinked.
