Yes, it does.
If you attend the SSPX and they find out you are "Resistance" you are out.
Even Bp. W mentioned it in the weekend's EC:
"The General Chapter of 2006 entitled the Society authorities to dismiss from the Society any priest disagreeing with their policies in public – “This warning is to be taken seriously.”
No matter how good are the dissenting arguments, public dissent always harms the common good."
No, it doesn't happen at all SSPX chapels.
It didnt happen to me at mine, and I make no bones about where I stand.
Bishop williamsons comment relates to priests who speak out, not congregation.
