A video review about the book of the same title along with some commentary. I found it informative to an extent. The video mainly is about Archbishop Thuc's life, but also Sedevacantism in general. In fact, the person who made this is none other than Serp Kerp, who had an account on this site and made some posts years ago, from what I can tell. He once was sede, but now supports the Conciliar Church, and so keep in mind that he is talking from a seemingly conservative Novus Ordo perspective. He even claims, (though this is to be expected) that Sedevacantism is "different religion" than Roman Catholicism. Since he was previously a sedevacantist, his knowledge about the different variations comes into this discussion, so he is more educated than most NOers who touch this subject. Be warned: if you browse around his channel, you'll see that he has placed images of immodestly dressed anime girls in the thumbnails of quite a few of his videos. That alone says to me that he seems to have "gone off the edge". Although I am not a sede, it saddens me that someone who was "red-pilled" on the Conciliar Church and Vatican II could wind up drinking their Kool Aid, and so I ask you all to pray for him (I will do so myself). 

I'm curious to how Sedevacantists on this forum would respond to two of his claims/opinions that stuck out to me: 

He also makes the claim towards the end that Sedevacantism is something that is "harmful" to the Church since their arguments are utilized by members of false religions to try to "disprove" the Papacy. How do sedevacantists respond to this? 

Another claim he makes in his conclusion is that Sedevacantism will grow in numbers, and prove to be a serious challenge to the Novus Ordo Church, due to the overall superior Internet savvy of their movement, higher birth numbers, and the lack of the Newchurch providing serious apologetics against sede arguments. (Note: he talks about how this growth will continue "to the end of the century" presupposing that the Chastisement will not have happened)
What do sedes make of this? 

Also, if anyone here has a better source about Archbishop Thuc, it would be appreciated.

I did a long interview with the Youtuber Classical Theist on my experience as a Sedevacantist and my current views.

I watched the first 45 minutes of the video. It provides a good analysis of the problems with sedevacantism in its various forms.
