Excellent analysis. And, yes, any thoughtful, fair review of both Pentin and Murray has to conclude they each are cheerleaders for the opposition to Pope Francis. I fully support their right to their opposition roles, but it's silly to deny there's an EWTN-Register "papal posse"  more aligned with Raymond Burke's Church view than with Francis's. 

Self-doubt isn't one of their traits. Ambiguity and nuance are their enemies. Trust in the laity and in theologians to "discern in the flow of life" (recent words of Francis) is minimal. 

When the Pope said we must sometimes eschew the comforts of  settling for "white and black" answers, I'm sure there was apoplectic reaction among those who more seek the comfort of canonical certainty than trust in the flow of life.

 They agree with the admonition of Archbishop Chaput that "confusion is of the devil." They disagree with John Wooden: "Learning is what happens after you know it all." 

 Arguing over  "The Joy of Love." Catholic irony lives!
