Short answer: Yes.
The SSPX is going downhill fast, with many CONCRETE ACTIONS that have been completed, and new orientations that have been made manifest through the official organs and statements of the SSPX.
As such, the SSPX is no longer the go-to group for the Resistance in the broad sense -- the Traditional Movement which resists Modernism, Fɾҽҽmαsσɳɾყ, Judaism, and Vatican II.
I think many would agree that their local SSPX chapel is far better than the Novus Ordo. It isn't dangerous to the Faith; the sermons might even be decent. But each and every SSPX priest is under the authority of Fr. Rostand, and must send a % of all collection proceeds up the chain to the District, and another % up the chain to SSPX Headquarters in Menzingen.
And if Fr. Rostand orders something, he has to carry it out.
The question is -- should we continue to support the SSPX, who has cast out Bishop Williamson and countless holy, faithful, courageous priests? I answer NO, we should not!
Just to be clear:
By "support" I mean financially. Attending their Masses is a different story. An SSPX Mass is valid AND not harmful to the Faith, so you can't sit at home on Sunday if there is an SSPX chapel reasonably close to your home.
I want OUT of the SSPX. If Bishop Williamson isn't welcome, than neither am I. I want my children to look up to real MEN like +Williamson and great priests like those in the Resistance. How will I ever expose my children to these holy clerics, if I continue to assist exclusively at my local SSPX chapel? It's not going to happen.
When it comes time for Confirmations, the SSPX will be sending any bishop EXCEPT Bishop Williamson. That, my friends, is NOT a good thing. How can you get a good +W sermon when +Fellay is the one doing confirmations? You can't.
It appears that many Catholics in the Resistance are in the same boat -- namely, they are NOT horrified by evil dripping from their SSPX priest -- because their SSPX priest is not evil and agrees with many points brought up by the Resistance. Some priests in this category even give decent sermons! At SSPX chapels with these priests, nothing has really "changed", or at least very little has.
In fact, it sounds like the average Catholic attending Resistance Masses has nothing personally against their SSPX priest. It's the SSPX they are opposing, and they want out from under it.
I fully agree. Under that aspect, I think it IS time to start Resistance chapels EVERYWHERE, NOW.
It's not about waiting for something bad to happen at your SSPX chapel. It's about getting a safety net ready BEFORE you need it. Remember, both priest AND Faithful need that comfort that they won't be out on the streets (or out in the cold without the Sacraments). Think of how much blackmailing power you take away from the bad guys, just by organizing an alternate chapel!
It's not your local SSPX priest that you're opposing. In fact, let him in on it! Recommend to your fellow Resistance parishioners that HE be supported directly with donations, rather than putting $$ in the general collection. Most places don't get Mass every week from the Resistance, and it's certainly NOT better to "stay home" than attend an SSPX Mass. An SSPX Mass is a valid TLM; it's not the Novus Ordo.
Give honor where honor is due; give support where support is due. Show your valued priests that you will support them DIRECTLY, WHEREVER they have to go to be faithful to their priesthood.
That way, they will be less likely to put up with Menzingen's ...crap... and they'll know who their friends are -- the faithful Catholics who wish to continue the legacy of the saintly Archbishop Lefebvre.
