It's not so much that the hierarchy is always talking about sex, but rather that the hierarchy has spoken about sexual mattes, and the left (and to a great extent, the right as well) has heard what the hierarchy had said, they don't buy into it, and they have moved on with their lives.  These theologians can sit around and hope for a new Reformation, but those to whom they are speaking have already had their new reformation, and it doesn't include the church.
