I think Bp. W's support base was once debated on Angelqueen and there was the idea that, if he were no longer a member of the Society, he would exit with a large chunk of the English-speaking world. Well, this never happened and even Fr. Morgan reconsidered his options. I think it has to be accepted that today's priests and laity are more worldly and circumspect than ever and do not see religion as all-embracing. If there are part-time trad priests that wear shorts 'out of hours' and pursue questionable hobbies, we may have moved into an era of salaried professional practioners. Once Menzingen accepts doctrinal freedom, then folk are given a free pass too enjoy today's goodies without penalty. And the specific traditional label really means an interest in a past culture and preserving quaint practices.
Profiling the Society's future membership and laity seems to be part of this great step (or leap) forward. Funds seem to be plentiful, so a cull of undesirables is affordable. BUt converting the Society into a small elitist body inside the overcrowded approved trad market would be a challenge. The defiant independent edge would be lost but maybe it would benefit greatly from Bergoglio-type excess and still remain in communion!
