I couldn't agree more.  
Catholics (regardless of the time they have spent as Catholic) are free to level well-founded criticisms at the pope, whoever he is.  It seems that MSW wants it to be that only American Cradle Catholics can level criticism about the Petrine Office, in the person of the pope, and that only against a more conservative pope or on very specific issues.  Do converts have no conscience to obey, as well?  And if those well-founded criticisms are echoed by many Catholics who have been so from their infancy?  I guess Hizhoner Spadaro already addressed that dilemma.
All that aside, I do appreciate the humility evinced in the final three-or-so paragraphs.
