Quit lying. Even from the very beginning the Holy See has said Catholics are permitted to attend SSPX masses so long as they’re not doing so as a formal act of schism, in accord with Canon Law 1248. So if you have an attachment to the Old Mass, then it’s perfectly fine, regardless as to whether or not it’s the only Mass (OF or EF) available.

Prof. Georg was the Professor of Canon Law, Law of Church-State Relations and Canonical HIstory from 1960 to 1994 at Mainz University. He has been a well-respected priest for more than 40 years in the Archdiocese of Mainz. The Professor’s conclusions appear to be consistent with those of the Holy See as expressed in numerous public interviews and written correspondence emanating from the PCED, specifically Cardinal Castrillón and Msgr. Camille Perl, president and secretary of the commission.
Code:
The SSPX is not schismatic, because she neither rejects the subordination to the Roman Pope nor rejects the communion with the bishops (can. 751). Rather the latter reject communion with the Society.
Because the Society is not schismatic, its members are not excommunicated. Both are untrue allegations, made by those, whom the reflective mirror presented to them by the Society irritates.
**Absolutely nobody incurs any punishment by attending the masses of the Society. Of course one can fulfill one's Sunday obligation by attending a Sunday mass in a chapel or church of the Society. Whoever alleges otherwise, reveals that he merely fears concurrence.***
Nail in the coffin of your theory.
