If you read my comment, you will see that I said it's not up to us to decide what is "authentically Catholic." There are many people who would accuse NCR authors and commenters of publishing hateful views, and we don't brand them as "inauthentically Catholic." There are many people who believe NCR and its commenters are "inauthentic Catholics," and we routinely decry their arrogance.
I don't subscribe to the narrow views espoused by the people named in this article, but I can say that without branding them.
