I recall seeing the story about his discussion with the Satmar Rav in a Jewish Observer article many years ago.
As to the fact that Reb Shraga Feivel held the Satmar Rav in high esteem – it is possible to respect someone but still not agree with him. The fact that history has moved on to the point where many of the views then expressed are either no longer relevant in current circumstances or shown to be wrong by subsequent events does not lessen the greatness of those who expressed those views. They were human, and reached their conclusions based on their understanding of the facts as they saw them.
