And the text of one email sent to them:
Dear Sir or Madam:
I am writing to express my full support of Archbishop Burke, and to relate my deep disappointment that you have chosen such a public example of anti-life (and, at its root, anti-child) advocacy as Sheryl Crow to perform at your fundraiser.
Cardinal Glennon wants to hide behind its noble purpose of helping children. Can’t you see the irony here? Rest assured that until the Hospital distances itself publicly from this event that my wife and I cannot financially support your institution.
Moreover, as a Catholic I am seriously concerned about the Catholicity of an institution that will not comply with the reasonable wishes of the local ordinary.
No amount of media approbation for your actions will make them right.
