Yes, we are living in similar times to V2 or covid, where the following are everywhere -- gaslighting, half-truths and social pressure to accept authority.
Yeah. Now, the SSPX also gaslight that it's the sedevacantists driving this attack on the validity of NO Orders becaues they "need themt to be invalid". Utterly ridiculous. As I mentioned, I would LOVE to be able to drive 5 minutes to see "Father Bob" down the street if I needed to go to Confession, and also to not pray that I would wait til the weekend (when the priest was in town) before dropping dead, and therefore having the opportunity to receive Last Rites. I have these lists I periodically update of retired pre-V2 Novus Ordo priests in the area we could seek out in an emergency, and that list gets shorter every year.
No, we do not "need" for them to be invalid any more than we "need" the Eastern Orthodox Orders and Liturgy to be invalid in order to recognize that they're schismatic.
Now, I would PREFER that New Orders be invalid in that I would prefer that Our Lord not be subjected to all the sacrileges and blasphemies to which He would be subject in the Novus Ordo ... but that's not a motivation here. I'm sure the Apostles would have preferred that Our Lord not be crucified, but at the end if God has willed that Our Lord be mistreated in the NOM like He was at His Passion, who am I to say otherwise.
But, no, there's no theological need that SVs have that the NO Orders be invalid. Zero.
On the contrary, the neo-SSPX have a political need to assert their validity ... since to say otherwise would be a non-starter for any talks with the Novus Ordo. "Hello, Mr. Prevost ..."
