That's certainly true. However, as you observed above, a fine liturgy does not, in the Episcopal church, directly correlate with a believing Christian congregation. And the Roman Catholic generation that grew up with your Sister Mary Attila and her fine rules of deportment abandoned their faith at the first whiff of a birth control pill. So what's up with that?
The answer to that question is easy, because it's happening again with Obama. When radicals gain control, they don't waste time with the "oh we mustn't upset people, we must respect their feelings" maunderings that well brought up people suppose that they should. They just jump in and CHANGE everything, all at once.
The generation of Sister Mary Attila came to Mass one Sunday and found the altar in the middle of the floor, the saints' statues gone, the confessionals gone, and Father seemingly having taken leave of his senses. They were told everything they had been taught was WRONG and STUPID and that the "new Church" was where it was at.
They felt abandoned and confused, and they left. The people who took VCII and used it as a cloak for their radicalization of the Church will have much to answer for at their particular judgment -- especially for the scandal to the faithful and a cause of their abandonment of their faith.
