Whenever neo-Catholics go on about how terrible, horrible, no good, very bad Traditionalists are, they're typically thinking of the ones old enough to remember the Ecclesia Dei regime. In his letter "Ecclesia Dei," St. John Paul II allowed the old Mass to be celebrated again with the permission of the local bishops. He encouraged the bishops to be generous in granting this permission. In practice, this meant the celebration of the old Mass was restricted to once a month, on a weekday, in the basement of the mental ward downtown or some such inconvenient time or place. It's difficult to overstate how passionately 1980s-90s era bishops despised everything that smacked of pre-Vatican II Catholicism.
Traditionalists picked up on this sentiment and returned it wholeheartedly. All they wanted was to live, pray, and believe the Catholic faith in the same way their grandfathers did, and yet their fiercest opponents were not the world, the flesh, and the devil but their own bishops! They became understandably bitter and distrustful toward the hierarchy. Hell, if I'd been in their place back then I would too.
Under Summorum Pontificum, a priest can celebrate the old Mass any where and any time he wants, in theory anyway. In practice, the old timers in the chancery still have a lot of bureaucratic tricks up their sleeve to ensure that doesn't happen. If Father gets a little too vocal in his preference for the old Mass and the old discipline, then he'll find himself banished to the diocesan equivalent of Siberia. He might have to shuttle between three different parishes out in the boonies, or spend the rest of his life in hospital or prison ministry.
Still, I remain optimistic. SP was the beginning of the end of the Spirit of Vatican II and the Modernists know it. The surviving members of the first generation of crazies are gathering what strength they have left for one last hurrah at the upcoming Synod on the family. That's not to say things will automatically get better once they go on to their eternal rewards. Father Z somewhat exaggerates the effectiveness of the biological solution. Even so, it's better to have lay Catholics and clergy who are simply ignorant of Tradition instead of furiously hostile to it.
