It doesn’t surprise me that a forgery is so often used to attack Cardinal Stepinac. What does surprise me is that it is STILL used even after being exposed by the reputed author himself and his family after him.
The “reputed” author? You mean you’ve found someone who claims to have done it and his words support the effort to excuse Stepinac’s murderous forced conversion campaigns?
Hey, did you also see the one Dan Rather has on George W. Bush?
