Personally, I don't think the criticism of Pope Francis is due to a misunderstanding of Vatican II but rather is the product of the conservative mindset which feels a certain entitlement to what it considers the absolute unerring truth, which only their side possesses.  Even the slightest deviation from their rigid dogmas must be met with total opposition and tight containment. As Americans we have seen this mindset at work with the Republican Congress during the eight years of President Obama's tenure. Cardinal Burke, in particular, is an exemplar of this mindset that must squelch all dissent rather than engage in dialogue in an effort to discern the truth, which more often than not is subtle and multi-faceted.  After thirty-five years of being in control conservatives in the Church are not going gently into that good night any more than Republicans did when Obama was elected. But unlike America, the Church is not a democracy, something the four mutinous cardinals should know well.
