Check out SGG website and one can find it out. Remember, we’re talking about viewing a Mass remotely. It doesn’t count for actual attendance.
The OP should define what he means by “Resistance.” Some people think of all Latin Masses as resistance—-against the novus ordo. Others draw the line at excluding indult and FSSP, others include SSPX. Still others have a narrower definition as having broken from SSPX in 2012, and some, get more specific than that, people who want only the “real resistance” v. the “fake resistance.” Then there’s the issue of sedevacantist, sedeprivationist, or R&R, una cuм v. non una cuм.
Again, do your own research! If you want the Mass of a particular priest or organization, you’ll probably have to request it of the priest. In the case of those who host Masses in their homes, many do not want the public to see inside their homes, their wives, children, and other attendees. That must be respected. The priest himself may not wish to be online. Example, Msgr. Vigano doesn’t livestream Mass for perfectly understandable reasons.
There is no moral obligation for anyone to put Mass online.
Well real "Resistance" would be the steadfast defense of the true Catholic Faith, characterized by:
-Unyielding rejection of all errors of the New Religion and the Conciliar Church, without justification, rationalization, or selective tolerance.
-Absolute fidelity to the Traditional Mass and sacraments, never conceding that the Novus Ordo can build or sanctify the soul.
-Courageous clarity in doctrine, refusing ambiguity, compromise, or silence when truth is threatened.
-Loyal support only for priests and bishops fully faithful to Tradition, not for those who compromise with error, for convenience, or for personal alliances.
-No participation in compromised structures or agreements with modernist Rome before Rome returns to Tradition.
-An uncompromising orientation toward the salvation of souls, rather than protecting institutions, reputations, or appearances.
-Firm Rejection of Sedevacantism.
