I understand where you are coming from, but I'm still very happy to learn that 20,000 adults will be baptised in France this coming Easter. Thats a 25 % increase over the previous year and many are getting baptised in traditional parishes.
Many baptise as adults because they see no political solution, and come from the extreme right or extreme left (many through healthy anti-semitism) and will move in a traditional direction when the novos ordo inevetably disappoints. There were many post covid adult baptisms in Saint Nicolas du Chardonnet, the SSPX flagship church in Paris.
There is a Marian Militia group at our SSPX parish and I have doing medalion distribution for the last few years. We go to the different villages, knock on doors and give the medallion, a page explaining how to say the Ave Maria and then talk if they want to talk. France is Catholic country, so this is clearly easier than in the USA, where this effort will be confused with all the various sects that also evangelise.
It's a very rewarding activity. Still no conversions as yet, but that's up to the people we meet. Typically, the younger people, under 40, are far more receptive than the old, who despite being in the extra-time of their lives, reject far more agressively anything to do with the Church.
The issues "BoD, BoB, EENS, sspx, resistance, sedes, una cuм, conciliar church" are difficult to adress and divide all traditional catholics, so having no authority I just up unless they ask my opinion. I don't even discuss them with most parishioners or the priest, but surprisingly many adult converts already know this issues and are less interested in compromise then the cradle catholics.
There are professedly 1 BN+ Catholics in the world. If even 10% or 100 MN took their faith seriously, and the duty flowing from their baptism and confirmation to evangelize, the world can be reached for King Jesus and Queen Mary in no time. About 100 people each per Catholic Evangelist would have to be reached, just about 25 homes or families should do it, assuming 4 persons per Family. It's never been easier to finish the Great commission. It's sad that some Catholics are not doing it, but God bless the good Catholics who are.
