I would have expected better from Catholic publications than branding one another as "inauthentically Catholic," whatever that means. I think if either of these authors were to spend a few days in, for example, rural Brazil -- the largest Catholic nation on earth -- where many Catholic communities have taken on the trappings of evangelical churches in an effort to survive without clergy, they might seek to work together instead of tearing apart what remains of the US church. 

My best guess is that the US Catholic Church will be a distant memory by the end of this century, precisely because its message has devolved into infantile debates about who is more Catholic.
