Mr. DeCuir - okay, a good point.  Allow me to raise some other perspectives:
a) Kung never silenced people; weighed in or judged colleague's works that impacted their careers and good names - so, one difference and stated reason for Weinandy hypocrisy
b) Kung is a well recognized, peer accepted, and acknowledged church theologian - Weinandy pales in comparison.  Kung has been in dialogue and has met with various popes and they have discussed theological interpretations (so, not sure your comparison works that well)
