The most recent General Chapter vote to oust Bishop Williamson was and probably sadly remains a telling sign of the state of the SSPX. Even laymen in association with the SSPX's publishing arm think Bishop Williamson is bad for business. Forget the fact that they dislike him because he offends their more sensible and 'prudential' minds on such things like history or ecclesiology.
Sadly, I would bet there is not a chance in Hades that His Lordship will be welcomed back to a house of the SSPX before the Lord is done with him on this rock.
The anti-Dinoscopus sentiment had been seminal in the SSPX since the Summer of 1994. I witnessed it with my own eyes and heard it with my own ears when in Winona. There are many a fair-weather-fan priest on the anti-Dinoscopus mailing list by now, particularly since the French Foreign Legion runs most autonomous houses in districts worldwide. I could only name 3 clerics who might even have the stones to house that 'eccentric lump of English plutonium'. They are castrated because of the fear of being 'swiss-fellayed'. I say, unabashedly there are a bunch of chickensh*ts in collars these days.
