Yes, some use this for an(other) excuse to attack Bp. Williamson. I know that's not how Wallflower meant it, but it does bring up the topic.
Which reminds me of the young accordista from St. Mary's, KS at my local Texas SSPX chapel -- we were discussing Bp. Faure's consecration, and his main argument was "it wasn't public enough".
I asked him, "Did you want to go?"
Silence, of course. "I thought so."
Ridiculous.
These people just want an excuse to indulge in their uber-convenient SSPX situation they've built up (or their parents built up) and are currently enjoying. It allows them to focus more time on themSELVES and their own fun, hobbies, pleasures, etc.
Those hobbies and pleasures are sure attractive (I'll be the first to admit it!) but we must be willing to put God FIRST if we're to keep the Faith, and have our children keep the Faith. God is putting us through a test right now.
