Papa Francesco also knows he is wrong on this issue.  We are seeing the political limits of how far Bergoglio can go at this time.  Papa Francesco is shackled with a priesthood and hierarchy that is dangerously alienated and hopelessly irrelevant to the lived experience of millions of Catholics and Christians.  

To paraphrase former Defense Secretary Donald Rumsfeld:  "You reform the church with the hierarchy you have, not the hierarchy you wish you had."  Papa Francesco is stuck with all these small, frightened men.
