Nah... When he speaks of unformed, he means that if you ask people my age (I'm a millenial) or younger about the tenets of the faith, they can only come up with moral platitudes that do not sound any different than any typical kid.  People are taught tenets without reasoning, so they disregard it, or they are taught whitewashed versions of the teaching of the Church, so they grow think there is nothing special about being a Catholic, leave the life of the Church and adopt a general modern somewhat synchretized theism.  Most Catholics are not educated to disagree with the Church... no, most are not even exposed enough to its teaching in any meaningful way to make a real decision about it.  I'm not maligning these people or calling it evil.  I'm simply giving my observations and experience as one who has lived and grown up with the children of those who experienced new modes of formation.  It's not even that we hate the Church... we don't even know it.
