The TFP is one thing, the TIA is another. When we talk about TIA around here, we place it under Atila's leadership and usually with the understanding that Atila is the only one carrying out Plinio's vision of what the TFP should have been. When we speak about the TFP, it's almost always in regards to its past with Plinio. The TFP as it is today hardly gets any airplay, but with Plinio and Atila gone they seem to have dialed back their initial fervor to the point that Bishop de Castro Mayer's condemnation hardly seems to fit them anymore, for better or worse. "Better" because they avoid getting involved with traditionalist infighting and "worse" because they shy away from VII.
TIA on the other hand, seems to have proved beyond a shadow of doubt that they won't be content to merely contribute to the growing scholarly criticism of the VII/NO faction (their efforts here were fantastic), but they must also act as TFP apologists and hatchetmen using some of the weakest standards of investigative journalism I have ever seen. And now that they've continued to set their sights on Archbishop Lefebvre with no other cause than to say 'we did it first and we did it better,' they've only exposed themselves as a compromised organization.
Note that when someone brought up the subject of Dr. Chojnowski's investigation of the two Lucys, all TIA could say was 'we did it first.' They couldn't be pleased that someone else was hoping to add to the discussion, they wanted all the credit :
