I listened to the whole presentation. It is a good start. From there they need to go into details in the conflict between the World and Catholicism lived (what he calls traditionalism). Remember, this is a youth conference. Are there other presentations that go into the details? What are some of the details that need addressing today? :
1) Relationships between boys and girls
2) Education
3) Entertainment vs self improvement
4) Work
A person can know Guerranger's Liturgical year and the Summa inside and out, and not know how to apply it in this world. For example, a parent who can even lecture on those texts, and yet allows his daughter to "date", to go out by herself with young men.
